Tweak Bird is an American rock duo known for their heavy yet melodic sound, a fusion of sludge, psychedelic rock, and hard rock, with touches of progressive and stoner elements. Comprising brothers Caleb (guitar/vocals) and Ashton Bird (drums/vocals), the duo hails from Carbondale, Illinois, and established their musical partnership in the mid-2000s. With Caleb's fuzz-drenched guitar and unorthodox vocal style paired with Ashton's thunderous drumming, Tweak Bird quickly carved out a niche for themselves within the rock scene for creating a colossal sound that belies their two-piece configuration.

Their self-titled release, "Tweak Bird," served as a formidable statement of their unique sonic identity and was succeeded by a string of critically acclaimed EPs and albums that showcase their evolutionary trajectory. "Undercover Crops," released in 2011, provided a compact blast of their signature sound, with seven tracks that display the duo's knack for crafting catchy, heavy music. In 2012, they put out "Reservations," a tantalizing teaser of what was to come, and by 2014, Tweak Bird delivered their most recent full-length offering, "Any Ol' Way." It's an album that found them refining and expanding their musical palette, integrating more complex rhythms and experimental sounds while maintaining the raw energy that has become their hallmark. Despite a relatively limited discography, Tweak Bird continues to enjoy a loyal following, appreciated for their unique merger of abrasive tones and infectious melodies on top of a deceptively simple setup.
