Disharmonic Orchestra are an Austrian death metal/grindcore band.

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.

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?
