A five man rock band without instruments, the House Jacks -- Bert Bacco, Deke Sharon, Garth Kravits, Wes Carroll, and Austin Willacy -- obliterate traditional preconceptions about the limits of the human voice, running the gamut from tender love ballads to dazzling mile-a-minute funk -- complete with mind-blowing vocal percussion and whammy-bar guitar sounding riffs. The jax have completed several successful world tours and have released three albums, most recently, Drive, a collection of live performances.
