Disharmonic Orchestra are an Austrian death metal/grindcore band.
The band was formed in Klagenfurt in 1987. Two demos were recorded. A gig in Germany with Pungent Stench led to a deal with Nuclear Blast in 1989. The first outcome of that deal was a split with country-mates Pungent Stench. After they released two full-length albums with Nuclear Blast they signed a new deal and released their third album on Steamhammer. The albums sound rather different from each other. The band took a break in 1994 . This timeout lasted until 2002 after their debut album Expositionsprophylaxe had been re-issued they released studio album, titled Ahead.
In October 2016 after a long break the band released their new album called Fear of Angst. In January 2023 the band released a compilation album of early demos, EPs, and previously unreleased recordings, entitled Repulsive Overtones? 1988-1989 on F.O.A.D. records.
