Planet Drum is a world music album by Mickey Hart, a musician and musicologist who was a member of the rock band the Grateful Dead. Hart's concept for Planet Drum was to play drum music with percussionists from around the world, and incorporate their different musical styles and traditions into a new global sound. The musicians on the Planet Drum album were from the United States (Hart), India (Zakir Hussain and T.H. "Vikku" Vinayakram), Nigeria (Sikiru Adepoju and Babatunde Olatunji), Brazil (Airto Moreira and his wife, vocalist Flora Purim), and Puerto Rico (Giovanni Hidalgo and Frank Colón). Planet Drum won the Grammy Award for Best World Music Album of 1991, the first year for which the award was given. It reached number 1 on the Billboard chart for Top World Music Albums.
