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. For their third album, Synchromysticism, the band has used these tools, as well as the drummer's (a clinical psychologist) understanding of signal detection theory and delusional mood to convey complex phenomenological concepts in a highly visceral form. This album, 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. This is post-apocalyptic dance music for the coming age.
