Praised by the likes of The New York Times, the BBC and even Ray Charles, the a cappella group, the House Jacks, create a full-band sound with only their five voices. The wildly talented quintet has shared the stage with James Brown, Train, LL Cool J, and Crosby, Stills and Nash, and played venues from Carnegie Hall to Candlestick Park. The group's repertoire features original tunes and covers, including songs by the Beatles, Led Zeppelin and more. The local teen a capella group 'Til Dawn opens the show.
