2nd II None is an American rap duo from Compton, California, comprised of cousins Deon "D" Barnett and David "KK" Barnett. They became known for their distinct blend of West Coast hip-hop and gangsta rap, marked by smooth beats and laid-back rhymes, which were prominent in the late 1980s and early 1990s. Their self-titled debut album, released in 1991, was produced by DJ Quik, a significant figure in the West Coast hip-hop scene. Despite a hiatus in the mid-90s, 2nd II None's influence on West Coast rap remains notable.
