Chicago's 90 Day Men evolved into one of the more distinctive math rock bands of the early 2000s, adding elements of psychedelia, '70s prog rock, and new wave to the angular, dissonant complexity that was the genre's stock-in-trade. Early on, their sound was a ragged post-hardcore art-punk indebted to Slint and their various Louisville brethren (Rodan, June of 44, etc.) as well as D.C.'s Dischord stable. As keyboards became an increasingly important part of their approach, however, they shifted into a more accessible, jam-friendly style, wrapping prominent piano melodies in droning, reverb-heavy noise. 90 Day Men broke up after ten years of steady evolution, their sound setting the scene for future noise makers that followed as the bandmembers pursued new projects. In 2024, the anthology collection We Blame Chicago compiled all three of the band's studio albums, as well as singles, EP material, a Peel Session, and outtakes.
