Thirlwell’s discography is extensive under many pseudonyms including Foetus, Steroid Maximus, Manorexia, Baby Zizanie, Wiseblood, Clint Ruin and others. If there is a common thread to his varied musical styles, it is dramatic intensity and evocative, cinematic quality. Thirlwell’s oeuvre stretches the gamut from orchestrations, big band, cathartic noise-rock to abstract electronics and sound sculpture, chamber music, serial music and imaginary soundtracks – sometimes all in the same album.
In recent years, with commissions for Kronos Quartet, Bang On A Can, and his occasional eighteen piece ensemble, he has been increasingly interested electronically and sample generated music being re-scored for traditional instrumentation – played both conventionally and not (recent examples include performing with a chamber ensemble version of Manorexia). Thirlwell is also a member of the “freq_out” sound-art collective, who create on-site sound and light installations led by curator Carl Michael Von Hausswolf. In addition, Thirlwell scores “The Venture Brothers”, a hit cartoon show on Adult Swim/Cartoon Network.
