Album: Busta Rhymes, Back on my B.S., (Island)

You might have had Busta Rhymes pegged as an outdated Nineties relic, but if that's true, nobody's told the American hip hop community.

For his eighth album, he has enlisted the help of countless first-division collaborators – including Lil Wayne, Pharrell, Mary J Blige and Common – and almost as many producers as tunes. His flows are surprisingly vibrant, and every now and then – the robo-rap of "We Want In" and the Neptunes-produced "Kill Dem" – the beats actually match Busta's enthusiasm.
