Dr. Dre is a hip hop legend whose production has shaped the sound of hip hop for three decades. With N.W.A he put California gangsta rap on the map in the 1980s. His 1992 classic The Chronic brought sticky funk to the masses and introduced Snoop Doggy Dogg. Whether Dre is working with 2Pac, Eminem, 50 Cent, or Jay-Z, he always finds a way to change the game. And his Beats By Dr. Dre headphones are changing the way millions of people hear music.
