Audioslave was an alternative rock supergroup consisting of [http://musicbrainz.org/artist/cbf9738d-8f81-4a92-bc64-ede09341652d.html|Chris Cornell] (formerly of [http://musicbrainz.org/artist/153c9281-268f-4cf3-8938-f5a4593e5df4.html|Soundgarden]) and the instrumentalists of [http://musicbrainz.org/artist/3798b104-01cb-484c-a3b0-56adc6399b80.html|Rage Against the Machine]. It has been disputed whether this band owed more to the sound of Chris Cornell's vocals, or the sound of the Rage Against the Machine instrumentalists.
