Black Star -
Mos Def & Talib Kwali Are Black Star (1998)
A hip-hop classic... Just first class in every aspect, over a decade old now but it's still a crowd-pleaser, forward-looking whilst utilising old skool, conscious hip-hop values to funky effect. There's more than a hint of ragga which is always good to see acknowledged, Barrington Levy gets a rep.
Unfortunately it's not on youtube for comparison here, but Mos Def delivers the first hip-hop cover version I've ever heard (Slick Rick's 'Children's Story') and flips the content to make it a scathing commentary on beat-pilfering mainstream fluff

The chorus from 'Definition' hijacks an old Boogie Down Productions refrain as well.
Essential!
