Former Grateful Dead drummer Mickey Hart's long career has given him legitimate icon status. Continuing to beat skins beyond his Dead days, Hart released Planet Drum in 1991, a record that earned the first-ever Grammy Award for Best World Music Album and remained #1 on the Billboard world-music chart for 26 weeks. Hart rejoined Planet Drum alums in 2007 for a follow-up album featuring Indian tabla master Zakir Hussain, Nigerian talking-drum virtuoso Sikiru Adepoju, and Puerto Rican percussion maestro Giovanni Hidalgo. The foursome takes the stage at Royce Hall for an evening of spellbinding drumming mixed with swirling electronic grooves.
