At least two bands are known under the name XYZ. 1. XYZ was a hook-laden heavy metal band. They were considered the unofficial house band of the Los Angeles nightclub The Whiskey in the mid 80's, but major success eluded them.
XYZ began in Los Angeles, California, with members Terry Ilous (vocals), Bobby Pieper (guitar), Patt Fontaine (bass) and Joey Pafumi (drums). An early development deal with Atlantic records led to the recording of their debut album, which quickly got radio play with the hits "Inside Out" and "What Keeps Me Loving You.

The quintet -- Ted Poley (vocals), Andy Timmons (guitar), Bruno Ravel (bass), Steve West (drums), and Kasey Smith (keyboards) Landed a deal with Epic in 1989. The same year saw the release of the group's self-titled debut, spawning the single/video "Naughty Naughty," which enjoyed a few airings on MTV's Headbanger's Ball program. The album failed to break the group through to the big time, but the group stuck to their guns and issued further albums: 1992's Screw It, 1995's Dawn, 1998's Four the Hard Way, and 2000's Return of the Great Gildersleeves.
