But what I would like to emphasize is an album anniversary. No, not the 50th of the eponymous Grateful Dead release. (But be sure to check out the newly remastered version, which comes with bonus live audio from July 29 and 30, 1966.) Instead, I wish to hail the 25th anniversary of the Planet Drum album. On Planet Drum, Mickey Hart drew together an ensemble of the world’s greatest percussionists: Zakir Hussain and T.H. “Vikku” Vinayakram (from India), Sikiru Adepoju and Babatunde Olatunji (Nigeria), Airto Moreira (Brazil, along with vocalist Flora Purim), and Giovanni Hidalgo and Frank Colón (Puerto Rico).
