As a teenager Rey played in punk band Shrapnel, which also featured Dave Wyndorf, later of Monster Magnet.
Shrapnel put out two 45 singles (Combat Love and Go Cruisin') and a five-song self-titled e.p., and played CBGB regularly in their brief career.
Rey did all of the guitar work for 9 of the 11 songs on Joey Ramone's 2002 solo album Don't Worry About Me.
Among dozens of other production credits, Rey produced both albums that the reunited Misfits did with replacement vocalist Michale Graves.
Rey recorded the theme song to Todd Solondz's cult comedy Welcome to the Dollhouse (1995), as well as a number of other tracks on the soundtrack.
