The Giant Crab. Their first single, issued on the indie label Corby in 1967, was a moderate local success in Southern California. Listen Girl had all the trappings of a mind altering masterpiece. But it just didn't crack the top-40 mold at the time and wandered into obscurity until the band was signed to Uni Records shortly after. This track never made it to any album, and not even to any compilation as far as I know.

It's one of those gems just waiting to be noticed.
