2. The album leaked nearly a year early. Pink Floyd developed the musical ideas that would become DSoTM on the road, playing early versions of the songs to audiences who, naturally, had no idea what they were listening to. By early 1972, the band was performing the full cycle, more or less. At their February 20 gig at London’s Rainbow Theatre, somebody liked it enough to record a bootleg.
The band was horrified when the bootleg appeared in record stores a year before the album was to be released, certain that the popular boot would harm the actual album sales. Somehow, we have to think they were ultimately satisfied with DSoTM‘s sales.
