Grateful Dead percussionist Mickey Hart's innovative Planet Drum CD convened some of the world's finest drum talent for a collaboration that won the very first GRAMMY for world music -- bringing together Nigerian drum legend Babatunde Olatunji, Indian tabla virtuoso Zakir Hussain, Nigerian talking drum ace Sikiru Adepoju, and Puerto Rico's master conguero Giovanni Hidalgo, among others. The 1991 album spent an unprecedented 26 weeks at #1 on the Billboard world music chart, and continues to sell as a perennial favorite.
