His latest solo CD is to me one of the best albums produced in the last, say, 5 years. This might not be an obvious CD for bass players, but the production and compositions, to me, are a as good as it gets. http://www.youtube.com/watch?v=pkIs5HGSKps
I've seen him live with Robert Glasper, and he's a monster player. His solos are very lyrical. No mechanical chops here.
He also happens to be Maxwell's musical director.
