On June 1st 1974, the Rainbow Theatre in London hosted the first ever performance by the greatest supergroup of the era. In the frontline: Kevin Ayers, John Cale, Brian Eno and Nico. In the backing band: Mike Oldfield and Robert Wyatt. On the fringes - a cast of thousands. A day-by-day guide to a generation's worth of classic albums, legendary concerts, mythic festivals and astonishing events, from Phun City to Hyde Park, from the Roundhouse to Reading, from the Belgian Woodstock to the Exploding Plastic Inevitable; and packed with exclusive interviews and material, ""June 1st 1974"" is the story of one magical evening, and - for the decade on either side of it - the careers that made it possible.
