Hear Pink Floyd’s previously unreleased, 15-minute version of “Interstellar Overdrive”

Record Store Day 2017 will bring a previously unreleased 14:57-minute recording from Pink Floyd’s “Interstellar Overdrive”... and music website "The Future Heart" has dug up what it claims to be that mysterious track, recorded by the band at Thomson studio in Hertfordshire, UK, at the tail end of 1966.

A previous RSD statement noted this unearthed version was recorded on November 30, however, studio records make no note of this; instead, "The Future Heart" points to an October 31st Pink Floyd session as the true source of this unreleased track.

According to various sources, this October 31 session yielded a demo version of “Interstellar Overdrive” that eventually served as the soundtrack for "San Francisco", a 15-minute documentary by filmmaker and Syd Barrett’s acquaintance Anthony Stern. Aside from its inclusion in the film, this recording, indeed, has never been officially released.
