red light fever
n.— «In terms of my own playing, it’s some of the most unselfconscious work I’ve ever put on record.…I kind of tricked myself into it; avoided the red light fever (a red light in the studio indicates that recording is in process) by telling myself I’m not making a record.» —“Let The Music Flow” St. Petersburg Times (Florida) Oct. 12, 1990.
