Tweak Bird is a collaboration between brothers Caleb (guitar, vocals) and Ashton Bird (drums, vocals), natives of Carbondale, Illinois (home to Southern Illinois University), who performed together on and off through the years before relocating to Los Angeles in the mid-2000s. Once there, they began molding an intriguing sound consisting of both modern (alternative, stoner, and post-rock, etc.) and classic influences ('60 and '70s psych, prog, and hard rock), which they previewed with a pair of 7" singles before issuing 2008's debut EP, Reservations, through Volcom Entertainment. After heading out on tours with Big Business and Tool, the duo went into the studio with production team Deaf Nephews (featuring Dale Crover of the Melvins and Toshi Kasai of Altamont), with their eponymous full-length arriving in 2010. The band hit the road with the Melvins in the summer of 2012, with a second EP, Undercover Crops, arriving later that year. ~ Eduardo Rivadavia
