Upon graduation, he joined the well-respected group HONK, an eclectic band that drew their influences from jazz, folk and rock.
In 1977 he joined KENNY LOGGINS and for the next twelve years honed both his live and recording skills. His subsequent years with great jazz artist AL JARREAU further broadened Tris' improvisational skills and earned him further acclaim on the international circuit.
Interspersed throughout those years he continued to play with a diverse list of artists in both live and studio sessions with such greats as Michael McDonald, David Foster, Julio Inglesias and Stevie Wonder, Crosby, Stills & Nash, Michael Paulo, Neil Diamond, Richard Marx, Brian Wilson, Steve Vai, David Sanborn and Stanley Clarke to name a few.
Since 1990 Tris has been the driving force behind the supergroup CHICAGO and continues his expansive reach to audiences around the world. With an exacting ear and decisive production technique, as musical styles evolve Tris continues to develop his talents as a producer and songwriter. He is also quick to share his knowledge through nationally sponsored clinics and workshops. As the grateful recipient of dozens of Gold, Platinum and Multi-Platinum awards, Tris is always eager to pursue new musical challenges.
