Deep Purple performed for the seventh consecutive night in a row at the Electric Circus on this day in 1968. They performed two shows.
Apparently, during this time period Deep Purple appeared with another band, Meat. I have been unable to find anything about that band anywhere, however. Given the Electric Circus’ penchant for multimedia presentations, it could have been something else going on at the same time. I talk more about the Electric Circus here.
No recording of either concert is known to exist. Mark I bootlegs are infamously rare; while records of their TV appearances and BBC sessions exist, most of their shows were not. Fragments appear here and there according to the Deep Purple Hub, but the only show of this entire lineup recorded in its entirety appears to be the Inglewood show of California.
