Take a trip through rocknrolls haziest, craziest period, beginning with the Beatles and Bob Dylan turning on in a New York hotel, and continuing on through two-decades of wonderful, colourful, history-changing music. From psychedelic Woodstock warriors like Hendrix and the Jefferson Airplane through psycho-stereo adventurers Pink Floyd; from the post-hippy bliss of Neil Young and cosmic cowboy Willie Nelson, to the druggy blues of Black Sabbath and the hemp-happy rhythms of Peter Tosh and Bob Marley, Out of Our Heads gleefully celebrates musics most creative minds and their chemically induced expansion.
