It's only fair that the drummer who invented Afrobeat pays tribute to the drummer who invented hard bop. For the last few years that Tony Allen has been enjoying a second youth in Paris and elsewhere, we have tended to forget that his very particular style, of touching and pounding, comes as much from his African and Nigerian sources as from the rhythmic boppers that were Kenny Clarke, Max Roach, and, in particular, Art Blakey.
