His band, Jartse Tuominen Group, is formed of the best Finnish musicians. Jartse´s music is instrumental rock with a jazzy flavor. "How to describe his music? Let´s assume that Billy Cobham, Steve Gadd, Al Di Meola, Steve Vai, Steve Morse, Billy Sheehan and Jaco Pastorius were in the audience at a Jartse Tuominen gig. They would certainly recognize aspects of their own music, but they would not be able to keep their butts on the bench." (Guitar Nine News)
