WMC-FM was the first radio station in the market, and the first in Tennessee, to play the Progressive Rock format on the FM band, beginning February 6, 1967, at a time when most FM stations played Frank Sinatra, Patti Page and easy listening instrumentals. Personalities included Greg Hamilton, Ron Michaels, Jon Scott, and David Day. The program director was Mike Powell. Artists included King Crimson, It's a Beautiful Day, and Quicksilver Messenger Service. The versions of "Light My Fire" by The Doors and "In-A-Gadda-Da-Vida" by Iron Butterfly (with its extended drum solo) were longer than the one most stations played.
