Most people think of Parliament-Funkadelic as a single entity in the annals of rock history (after all, they went into the Rock and Roll Hall of Fame as one unit in 1997). In 1974, specifically Dec. 12 for their show at the Tomorrow Club, the band was actually two separate entities who were touring together. Parliament was the funk and R&B remnants of an old doo-wop/Motown style act developed by George Clinton in the 1960s. Funkadelic was the backing band which made music based on the psychedelic rock styles of the late 1960s. All of this began to fuse in the mid-70s and the band would enjoy huge success in the middle part of the decade.
I’m not sure what went on in 1974 in Youngstown. No one really cared to chronicle setlists or concert itineraries from that period from what I can tell. There is also no accurate bootleg record from that era either.
