Their first release was the "Flexible Membrane" flexi-disc in 1980, and over the next 11 years they went on to release six studio albums. Their first single proper, "Muscles", was a single of the week in the UK music press and a big club hit in New York being played in the Danceteria by the Beastie Boys eventual DJ Mojo and other New York DJs. Kelly left after "Muscles", to be replaced by Steve Farmery on guitar for the follow-up "Pin Stripe Hype" EP.
