Strident, soul-searching lyrics amid apocalyptic auras, tricky time signatures and a profusion of triplet note clusters tells the listener he’s in the realm of progressive rock. And while Initial Mass bring nothing new to the genre, they do an able job of capturing its essence. Whether it’s “Light,” “The Fountain” or the blues-infused “Cold Air,” these musicians comprise a tight unit that steers an obstacle course of twists and turns in each arrangement. The latter song, a majestic, melodramatic acceptance of death, shows off singer Mark Baldwin’s ability to hit the high notes. Still, we feel there’s an overall need for the band to leave its safe, familiar territory for a higher, rarified altitude.
