Since the early nineties, working “in the cracks” between the Jazz Avant Garde, Contemporary Classical and Alternative New music traditions, Tom has developed a unique name for himself as the leader or co-leader of six contemporary Canadian groups: Walsh/Underhill, with Toronto’s own sax genie, Richard Underhill; Midi tapant (High Noon), digital/acoustic adventures with Pierre Tanguay& “found-sound"; Swifty Lazarus, experiments with sound/media manipulations & Todd Swift’s spoken word; Pots & Pans, a six piece modern cabaret “pit orchestra of the mind"; Royal Jelly, an exclusive hiphopjazz party band; and, last but not least, the infamous “7-headed hydra” known as Noma, perhaps Canadian jazz’s first harmonic de-scaler.

More recently, Tom completed an Eastern European solo trombone concert tour in 2000. On record, he’s featured on more than 40 national or international releases (from most of the names above), including a healthy dose of the Ambiances Magnétiques catalogue.
