With the birth of hip-hop occurring 44 years ago and particularly traced to a fateful Bronx back-to-school party in August 1973 - Google celebrates hip-hop''s birthday by unveiling a new interactive doodle on its home page.Partnering with legendary graphic artist and designer Cey Adams and the pioneering artist/host Fab 5 Freddy, Team Google Doodle traveled to the New York studio of Adams in order to create the tech titan''s most dazzling work of interactive art yet.Adams emerged from New York''s graffiti movement alongside Basquiat and Haring, and so he witnessed firsthand how such visual art blended with the rise of hip-hop."First and foremost, the [visual] art component predates the other art forms," Adams tells The Washington Post. "Certainly music has been around, but when it comes to graffiti - that''s been around since the late ''60s. It was a thing unto itself, that had its own movement.""So by the time the late ''70s came around, and all the elements become a collective," Adams continues, "graffiti art took a back seat to rap music. Music has always been universal. Music lives in the air, music is everywhere - it doesn''t cost you anything.""That said, hip-hop is a visual movement, [and] graffiti will remain a necessary element of creative expression within the culture," he added.Also tapping the talents of Lyor Cohen, the global head of music for Google-owned YouTube and the former Def Jam president - Cohen says on Google''s blog that hip-hop "shows that people in any situation have the ability to create something powerful and meaningful. The progression of this culture and sound - from Kool Herc spinning James Brown breaks at a block party to Jay-Z, Kanye West and Drake being some of the biggest forces in music 44 years later - is something that few people at that first party could have anticipated."If you haven''t done so yet, check out Google''s home page now as Fab 5 Freddy narrate''s the home-page where you can view a quick glimpse of hip-hop''s history, toward a tutorial of pulling tunes from the digital crate and working the turntables.
