Twin Infinitives is the second album by Royal Trux. It was released as a double LP in 1990 by Drag City, then reissued on CD and cassette in 1994. The album is noteworthy as the first full-length album released under Chicago independent label Drag City.
Twin Infinitives is noted for its deconstructed arrangements, unorthodox vocals and dense production; all were extremes rarely visited to the same degrees on Royal Trux's later releases.
