Besides pioneering the transition from bebop to hard bop, hard-swinging drummer Art Blakey was a relentless experimentalist. The 1947 trip to Africa that intensified his already polyrhythmic style also inspired the Afro-Drum Ensemble's "Love, the Mystery Of"; the richly interactive "A Chant for Bu"; and whirlwind solos like the thunder-and-lightning repercussions of "New World."
