Big Organ Trio is currently vying for a New Groove spot via our Jambands 250 poll and last weekend, a 1970s keyboard sensation stopped by to show his support. While perform at Santa Monica, Californias O’Brien’s, Keith Emerson, (Emerson, Lake and Palmer) emerged for a cover of Freddie King’s ‘Hideaway.’ The keyboardist returned during the group’s second set for an additional, more improv-oriented jam. Big Organ Trio will support the New Mastersounds at Santa Cruz, CA’s Moe’s Alley on April 20.
