This Busy Monster was an American indie rock band formed in Seattle, Washington in the early 1990s. The band was composed of Christopher Possanza (vocals, guitar), Josh Rosenfeld (bass guitar), Jason Avinger (guitar, vocals) and Barrett Wilke (drums).

Known for their unconventional song structures, and eclectic instrumentation (including the use of a clarinet in many tracks), the band released three full-length albums, Like Icicles, The Curious Sofa and Fireworks, and released many EPs.
