Terry helped form the original line-up of The Aquabats in 1994 alongside fellow musicians Christian Jacobs and Chad Larson, all of whom knew each other through mutual friends in The Church of Jesus Christ of Latter-day Saints (LDS Church). According to Larson, it was Terry's presence which was largely responsible for The Aquabats deciding to start out as a ska band with a horn section, as both he and Jacobs had wanted to include Terry as a member despite the trumpet being the only instrument he could play. Terry is also credited for creating the band's iconic costumes, having personally stitched together their original custom rashguards and helmets from spare lycra and neoprene he acquired from Aleeda, a wetsuit-manufacturing company both he and his brother worked for at the time.
During his tenure with The Aquabats, Terry played trumpet and similar valved instruments on all of the band's recordings from their 1994 demo tapes to the 2000 compilation Myths, Legends and Other Amazing Adventures, Vol. 2. He has been credited with writing or co-writing several of the band's songs, most notably "Pool Party!" and the b-side "Mucho Gusto", on which he also sang lead vocals. During The Aquabats' career lull in the early 2000s, Terry amicably parted ways with the band in 2002. His departure was informally announced on The Aquabats' website in a September 7, 2002 news update, facetiously stating that a vague "terrible accident" had left him "incapacitated indefinitely...allegedly".
Since leaving The Aquabats, Terry has pursued a career in apparel design, having worked for both RVCA and Nike. In the fall of 2009, he briefly re-joined the band to play a series of holiday shows throughout Southern California, and in 2012, he made a cameo appearance in the "Showtime!" episode of The Aquabats' television series The Aquabats! Super Show!, playing a superhero appropriately named "Catboy".
