Since 2000, St. Louis YOWIE has been perfecting a unique form of progressive rock that incorporates complex polyrhythms and guitar dissonance. Operating within its own unique idiom, Yowie rejects rock music s typical foundation of common time signature and standard melodic structures. Their third album, “Synchromysticism,” the first with guitarist Christopher Trull (formerly of Grand Ulena), marks a new level of ambition in terms of conceptual complexity, synthesizing opposing compositional approaches into a distinctive style that simultaneously elicits feelings of euphoria, perplexity, dread... and an inexorable urge to dance.
