Released in 1962, This Is It is an imaginative cacophony of percussion, non-verbal chanting, and free-flowing expression, punctuated occasionally by leisurely passes at a terrestrial piano, marimba, or french horn. It is at once, experimental, intellectual, and experiential. Three years before Ken Kesey’s inaugural Acid Test, This Is It! constitutes the first transmission for a tuned-in counterculture of hippies, beats, and psychedelic revolutionaries of all stripes.
