Is THAT what was going on? You know the controversy about the "Tejas" album? It was released in 1976 on record with a human drummer. But at some point they replaced the drum track with a much more aggressive synth drum track and that's all that's been available unless you have the original vinyl.
I wonder if they were trying to retcon their style?
Old enough to remember them blaring out of every car's 8-track player at the beach.
