Records such as Triumph’s new Progressions of Power make it easy to understand why new wavers with something to say have seemed like such a breath of fresh air. Like umpteen other mainstream rock outfits, Triumph delivers heavy-handed music that’s strictly of the you’ve-heard-it-all-before variety: lots of histrionics, heavy-metal clamor, and lines about rock and roll machines, party scenes, and mindless dreams. Suggested alternate title: Regressions of Power.
