There are 5 acts known as Painkiller

* [1] Painkiller are a jazzcore band, originally formed in 1991. Their style can be described as a mix of avant-jazz and grindcore that places them in the sub-genre of jazzcore. Later albums also incorporated elements of ambience and dub.

The three primary members of the band are: John Zorn on saxophone, Bill Laswell on electric bass and Mick Harris (formerly of Napalm Death and founding member of Scorn) on drums. The band has also had several musicians make guest appearances both live and in the studio, including Yamatsuka Eye, Kevin Sharp of Brutal Truth, Buckethead, Mike Patton, Makigami Koichi, Liu Sola, Justin Broadrick and G.C. Green of Godflesh, and Keiji Haino of Fushitsusha.

In 2005, Mick Harris (drums) left Painkiller. The band has been playing live shows since, using various drummers, amongst them Hamid Drake - who appears on the live recording "50th Birthday Celebration Volume 12 (Tzadik) - and Yoshida Tatsuya (Ruins). As of 2008, Mick Harris has returned to drums appearing live in Paris with Zorn & Laswell.
