Thelonious Monster is an American punk rock band from Los Angeles, California, led by singer-songwriter Bob Forrest and named after jazz musician Thelonious Monk. Active from 1984 to 1994, again from 2004 to 2011, and reforming a second time in 2019, the band has released five original studio albums. It has been described as having "traced emotional dips and bends with exceptional acuity and impact".
