West Coast Rap is a genre of pop music. The representative N.W.A adds a stronger voice to its grinding vocals and market content. In addition, it maintains Its original function as party music made it a major force in hip-hop in the 1990s.
2. East Coast
Nas, Mobb Deep, Juru the Damaj a, etc.
Public Enemy, Boogie Down Productions, Run-D.M.C. and other elite East Coast artists drew directly on the simplicity and directness of their predecessors, contrasting with the glamor of the West Coast. The result is a more angular rhythm and a rigorous yet powerful rhyme. As the East and West coasts merged, rap became the alloy of cross-strait cultures, and the clear and crisp East Coast sound continued to flourish.
Faction:
Influenced by Hip-Hop predecessors such as Grandmaster Flash and Afrika Bambatta, West Coast rap is further away from old-school rap than East Coast rap. They use a more "funky" unique rhythm, supporting smooth, melodic tunes. West Coast rappers were also the first to bring the good and bad of "gangster" culture to the forefront of Hip-Hop culture.
Although the lines between East and West Coast rap are slowly fading as rap continues to evolve, there is still a distinct West Coast system, ranging from quintessential rap group N.W.A. to Snoop Dogg and Vallejo, as well as California's E-40, etc.
Extended information:
The origin of rap music:
Rap music originated as a cross-cultural product. Most of its important early practitioners including Kool Herc, D.J. Hollywood, and Afrika Bambaataa were first-generation Americans of either immigrant or Caribbean ancestry. Herc and Hollywood are credited with introducing cutting-edge Jamaican styles and mixing them into the musical culture of the South Bronx.
By most accounts Herc was the first DJ to buy two copies of the same record for the 15 second break (the rhythmic instrumental section) in the middle. By mixing repeatedly between two copies he can double, or indefinitely triple the break. In doing so, Herc deconstructed and effectively recreated the so-called found sound, using the turntable as an instrument.
The origins of rap music can be traced back to the chanting passages in the roots of black music. By the 1970s, rap music had officially established its own style. The main contribution was attributed to the popular disco music at that time. DJs mixed the funk rhythms that were popular among black people at the time into the popular disco rhythms, and repeated the contents of the same record on the record player to create their own LOOPS.
