With their stock rising among hard rock fans, Triumph inked a new recording contract with MCA, which led to their most successful period both artistically and commercially. Such resulting albums as 1979's Just a Game and 1980's Progressions of Power inched the group closer to breakthrough success, which was obtained by a pair of back-to-back gold-certified albums: 1981's Allied Forces (often considered the group's best album, which spawned the hit anthem "Fight the Good Fight") and 1982's Never Surrender. Such further albums as 1984's Thunder Seven, 1985's Stages, 1985's The Sport of Kings, and 1987's Surveillance failed to meet the expectations set by their earlier releases, yet the group was able to retain its following. Come 1988, Emmett opted to leave the group to pursue a solo career, but instead of calling it a day, Moore and Levine decided to carry on with a new frontman/guitarist, while an 11-track best-of set, Classics, was issued a year after Emmett's exit.
Their first choice, ex-Thin Lizzy/Whitesnake member John Sykes, was too busy getting his project Blue Murder off the ground at the time, so the gig ultimately went to former Frozen Ghost/Aldo Nova associate Phil X (it was also around this time that the group built their own recording studio in Mississauga, Ontario, called Metalworks). The Phil X-led version of the group only managed to issue a single release however, 1993's Edge of Excess, before Triumph split up for good. In the wake of their breakup, several archival releases popped up in record stores, such as 1995's In the Beginning and 1996's King Biscuit Flower Hour (the latter of which chronicled a 1981 concert), while Rik Emmett continued on with his solo career, issuing albums on a regular basis throughout the '90s. ~ Greg Prato, All Music Guide
