Tetrafusion is a Louisiana-based progressive metal band established in 2006. The band’s mix of complex, technical metal blended with a highly-intellectual melodic structure offers an eclectic brand of progressive rock and metal pushing the edge of contemporary music today. Originally an instrumental band, the group released its debut record "Absolute Zero" in 2009 to critical acclaim, which quickly launched the band into the underground metal scene, sans vocals.
