The Evolution of Rap and Hip-Hop Styles: From Boom-Bap to Trap, Drill, and Beyond

Over the past 50 years, rap has grown from a local sound born in the Bronx to a global cultural force.

As the genre has grown, so has its cultural impact. Rap and hip-hop have changed music, fashion, and language worldwide and will continue their front-and-center role in global music culture. 

Now widely known as the most popular genre of all time by total record sales and streams, hip-hop continues to expand – proving itself time and time again as a music style that truly thrives on change. 

Let’s whip through a short odyssey of hip-hop, investigating its evolution and key moments along the way. 

From the Bronx to the World: Old School Hip-Hop (1970s-80s)

In the 1970s, a new sound was brewing in the Bronx. At block parties and park jams, DJs began looping the breakbeats of funk and soul records, while MCs rapped over the beats to hype up the crowd. 

This fusion of rhyme and rhythm would grow into one of the most influential cultural forces of the late 20th century: hip-hop. 

The Birth of Hip-Hop

Rap's origin story begins with pioneers like DJ Kool Herc and Grandmaster Flash, who developed techniques like breakbeat looping and scratching at Bronx block parties in the early 70s. 

As MCs began rapping over these beats, the basic elements of hip-hop fell into place, which included the dynamic interplay of DJ and MC, the emphasis on rhythm and flow, and the competitive spirit of park jams and battles.

The Rise of the Old School

As the decade progressed, rap started to spread beyond the boroughs of NYC. The Sugarhill Gang's "Rapper's Delight" became the first rap song to crack the Top 40 in 1979, introducing the genre to a wider audience.

Grandmaster Flash and the Furious Five's "The Message" in 1982 marked a shift towards socially conscious lyricism, proving that rap could tackle serious subjects – which would be absolutely instrumental going forward.

The Golden Age 

The mid-to-late 80s saw the rise of the "Golden Age" sound, characterized by heavy sampling, advanced rhyme schemes, and the now-iconic boom-bap production style. 

Iconic groups like Run-DMC, Beastie Boys, and Public Enemy brought rap to the mainstream with crossover hits and a brash, unapologetic attitude. 

This era solidified rap's musical identity and set the stage for the genre's massive cultural impact in the decades to come.

Regional Scenes Emerge

As hip-hop gained national attention, we began to see regional scenes emerge outside of New York. 

Philadelphia's Schoolly D pioneered gangsta rap with his gritty street tales, while Los Angeles artists like Kid Frost and Ice-T laid the groundwork for the West Coast sound that would dominate the 90s.

The 90s: Hip-Hop Surges Onwards

The 1990s was the decade that saw the genre reach new heights of creativity, diversity, and commercial success. 

From the gritty realism of gangsta rap to the laid-back grooves of G-funk, from the lyrical prowess of the East Coast to the rise of the South, the 90s produced some of the most iconic and influential music in hip-hop history. 

But it was also a decade marked by tragedy, with the deaths of several prolific artists, most famously Biggie and Tupac.

The West Coast: Gangsta Rap and G-Funk

The West Coast sound dominated the early 90s, with gangsta rap and G-funk soaring in popularity. 

Groups like N.W.A and solo artists like Ice Cube pioneered gangsta rap, with its unflinching portrayals of street life and scathing critiques of systemic racism. 

Meanwhile, Dr. Dre's G-funk sound, characterized by funky basslines and melodic synths, brought a smoother sound to the West Coast style. Snoop Dogg's Doggystyle (1993) and 2Pac's All Eyez on Me (1996) became iconic albums of the G-funk sound. 

The East Coast Renaissance

The mid-90s saw a creative explosion in New York, as artists like Nas, The Notorious B.I.G., Jay-Z, Wu-Tang Clan, Big L, and Big Pun pushed the boundaries of gritty lyrical and storytelling technique. 

This era produced some of the most acclaimed albums in hip-hop history, but was also marked by the tragic deaths of Biggie, Tupac, Big L, and many others, and the escalation of gang violence and the East Coast-West Coast feud.

The Rise of the South

While the East and West Coasts battled for supremacy, the South was quietly building its own distinct sound. 

OutKast and Goodie Mob put Atlanta on the map with their eclectic, soulful brand of Southern rap, while UGK and Geto Boys represented for Houston with their gritty, syrupy beats and vivid stories from the streets.

Jazz Rap and Alternative Sounds

The 90s also saw the rise of jazz rap, as groups like Gang Starr, Guru, Digable Planets, and A Tribe Called Quest blended jazz samples and live instrumentation.

The Native Tongues collective, which included Tribe, De La Soul, and Jungle Brothers, pioneered a more positive, Afrocentric style as an alternative to gangsta rap.

International Success

While the 1990s saw hip-hop solidify its place in the American mainstream, the decade also witnessed the genre's global dissemination. 

In Europe, groups like the UK's Stereo MCs and France's MC Solaar began rapping in their native languages and infusing hip-hop with their own cultural influences. 

In Japan, artists like DJ Krush and Scha Dara Parr helped establish a vibrant Japanese hip-hop scene. By the end of the decade, hip-hop had become a truly worldwide phenomenon.

2000s: Hip-Hop Takes Over the Mainstream

The 2000s saw hip-hop complete its transformation from an underground, counter-cultural movement to a dominant force in mainstream popular culture. 

Rappers became global superstars, hip-hop albums routinely topped the charts, and the genre's influence could be felt across fashion, film, television, and advertising. 

The decade also saw the rise of new regional sounds, the blurring of genre boundaries, and the emergence of the rapper as a multi-platform entrepreneur.

The Bling Era and the Rise of the Rap Mogul

The early 2000s were characterized by a glossy, materialistic aesthetic known as the "bling era." Producers like The Neptunes and Timbaland crafted sleek, radio-friendly beats, while MCs like Jay-Z, Lil' Kim, and P. Diddy celebrated the luxuries of the hip-hop lifestyle.

This era also saw the rise of the "rap mogul," as artists like Jay-Z, 50 Cent, and Diddy launched successful brands and business ventures, cementing hip-hop's place as a commercial powerhouse.

Crunk, Snap, and the Dominance of the South

The South, which had been steadily gaining prominence since the 90s, took center stage in the 2000s with the rise of crunk and snap music. 

Crunk hits like Lil Jon & The East Side Boyz's "Get Low" and Three 6 Mafia's "Stay Fly" dominated the clubs, while snap tracks like D4L's "Laffy Taffy" and Soulja Boy's "Crank That" became national dance crazes. 

Southern hip-hop's ascendance reflected the genre's growing regional diversity and mainstream appeal.

Kanye West and the Hip-Pop Revolution

Kanye West's debut album "The College Dropout" (2004) marked a turning point in hip-hop's relationship with pop music. 

West's "chipmunk soul" production style and introspective, emotionally honest lyrics set him apart from his gangsta rap peers and paved the way for a new generation of MCs who blurred the lines between rap and R&B. 

Artists like Drake, Kid Cudi, and West himself incorporated singing and melodic hooks into their music, creating a new, pop-friendly subgenre sometimes dubbed "hip-pop."

International Subgenres Grow

The 2000s saw the emergence of grime, a distinctly British take on hip-hop that blended rap with electronic music influences. 

Pioneered by artists like Dizzee Rascal, Wiley, and Kano, grime reflected the experiences of young, urban Britons and became a major force in UK music. 

The decade also saw the rise of international hip-hop stars like Canada's Drake, who would go on to become one of the most successful rappers of all time.

Hip-Hop as a Global Cultural Force

By the end of the decade, hip-hop had become a truly global phenomenon. 

Eminem was a household name, Jay-Z was rubbing shoulders with presidents, and rap music was the soundtrack to movies, TV shows, and advertisements worldwide. 

Hip-hop fashion set trends from the streets to the runways, and rappers were among the most followed celebrities on the then-nascent social media platforms. 

2010s: Blog Era, Trap, Chicago Drill & SoundCloud Rap

The 2010s was a decade of rapid change and innovation in hip-hop, marked by the rise of new regional scenes, the dominance of trap music, and the immense influence of the internet. 

The blog era saw a new generation of MCs gain prominence through online platforms and social media, while trap music from the South took over the charts. 

Chicago drill and SoundCloud rap also emerged as distinct subgenres, each with their own more DIY sounds, styles, and online impacts, eventually breaking from the internet to become some of the most successful styles of hip-hop from the era. 

The Blog Era

In the late 2000s and early 2010s, hip-hop blogs like Nah Right and 2DopeBoyz became influential, bringing breaking new artists to the fore and steering the conversation around the genre. 

MCs like Kid Cudi, Wale, and J. Cole first gained traction through blog buzz, before going on to mainstream success. 

The blog era was characterized by a diversity of sounds and styles, from Kid Cudi's introspective, melodic approach to J. Cole's more traditional, lyrically-focused hip-hop.

The Trap Takeover

As the decade progressed, trap music from the South became the dominant sound in hip-hop. 

Pioneered by artists like T.I. and Jeezy in the 2000s, trap exploded in the 2010s with the rise of Future, Migos, and other Atlanta-based MCs. 

Trap beats, characterized by booming 808 bass, skittering hi-hats, and ominous synths, became the default sound of hip-hop production. 

Lyrically, trap often focused on themes of drug dealing, street life, and the perils of fame and success.

The Chicago Drill Scene

While Atlanta dominated the mainstream, Chicago was brewing its own distinct scene known as drill. 

Pioneered by artists like Chief Keef and Lil Durk, drill was characterized by its dark, gritty beats and its bleak, often violent lyrics. 

Drill reflected the harsh realities of life on Chicago's South Side, and its influence could be heard in the work of artists like Pop Smoke and other practitioners of Brooklyn drill in the late 2010s.

SoundCloud Rap and Emo Rap

The latter half of the 2010s saw the rise of SoundCloud rap, a loosely defined subgenre that emerged from the streaming platform. 

Artists like Lil Uzi Vert, XXXTentacion, and Juice WRLD blended elements of hip-hop, punk, and emo, often focusing on themes of mental health, drug use, and existential angst. 

SoundCloud rap was characterized by its lo-fi, DIY aesthetic and its rejection of traditional hip-hop sounds and structures.

Late 2010s-Present: Melodic Rap, UK Drill & Whatever's Next

As we entered the late 2010s and early 2020s, hip-hop continued to evolve and splinter into new subgenres. 

Melodic rap, influenced by the sing-song styles of artists like Future and Young Thug, became increasingly popular. 

UK drill, a regional offshoot of Chicago drill (though that is debated) and heavily influenced by UK grime, entered the mainstream. 

Latin trap also had a major moment, reflecting hip-hop's increasingly global reach.

The Rise of Melodic Rap

Melodic rap, which blends singing and rapping over trap-influenced beats, became a dominant style in the late 2010s.

Artists like A Boogie wit da Hoodie and Roddy Ricch scored massive hits with their melodic, auto-tuned flows, while established stars like Drake and Travis Scott also incorporated more singing into their music. 

The lines between hip-hop and R&B became increasingly blurred, reflecting a broader trend towards genrelessness in popular music.

Hip-Hop Becomes Dominant 

The 2010s saw hip-hop truly go global, with artists from around the world making waves in the genre. 

Canadian rapper Drake became one of the decade's biggest stars, fusing hip-hop with R&B and pop influences. 

British rappers like Skepta and Stormzy brought grime to international audiences, while Australian artists like Iggy Azalea and The Kid LAROI climbed the US charts. 

Latin trap artists like Bad Bunny and J Balvin also made major crossover moves, reflecting hip-hop's increasingly multicultural and multilingual future.

UK Drill Crosses the Atlantic

While drill music originated in Chicago, it found a second life in the UK, particularly in London. 

UK drill, pioneered by artists like 67 and Headie One, took Chicago's dark, gritty sound and added elements of UK grime and road rap. 

In the late 2010s, UK drill started to make waves in the US, with the late Pop Smoke becoming the scene's biggest crossover star. Other artists like Fivio Foreign and Sheff G also found success blending UK drill sounds with Brooklyn swagger.

Latin Trap Goes Global

The late 2010s also saw the global rise of Latin trap, a Spanish-language offshoot of trap music. Artists like Bad Bunny and J Balvin became international superstars, blending trap beats with reggaeton rhythms and Spanish-language lyrics. 

Latin trap reflected the increasingly multicultural and multilingual nature of hip-hop, and its influence could be heard in the work of English-language rappers like Cardi B and Tyga.
