Although the album Nomadic Sands failed to chart in the U.S., the first single Lonely Man was featured in the movie Prince of Bel Air, starring Mark Harmon & Kirstie Alley.

Recording their progressive self-titled debut album in 1988, produced by Keith Olsen, this group included ex-Lodgic bandmate Billy Sherwood along with Bruce Gowdy and Mark Williams.

After the breakup of World Trade, Allison was tapped by Graham Russell to join Air Supply in the recording studio and ultimately on tour.

During his time with Air Supply, he and ex-World Trade bandmate, Bruce Gowdy, formed the harder edge Unruly Child with singer Mark Free.

Signed by Interscope Records and produced by Beau Hill in 1991, Unruly Child, (whose members included Larry Antonino and Asia's Jay Schellen) found cult status overseas yet remained undiscovered in the U.S. After Unruly Child disbanded, Allison continued to tour with both Air Supply and Japanese artist Eikichi Yazawa.
