Angel Dust (originally Angeldust, not to be confused with many other less successful/lasting bands of the same name) is a power metal/ Speed Thrash Metal band originating from Dortmund, Germany that started off as a typical garage band. Taking their name from a song title off the black metal band Venom's debut album Welcome To Hell, Angel Dust was founded in 1984. Their style was initially heavily influenced by the NWOBHM metal scene and the Bay Area thrash metal scene. They soon found their niche in the speed and thrash metal styles which were widely popular at the time. The 1980s would see two releases from the band: 1986's Into the Dark Past and 1988's To Dust You Will Decay. They proceeded to disband in 1990because of internal conflicts.

Although all members had gone their separate ways, founding member Frank Banx had no desire to let the Angel Dust name die. Around 1998 Banx, and original drummer Dirk Assmuth, gathered a completely new lineup (including Frank Banx' younger brother Steven Banx on keyboards) to start from scratch. This reincarnation would handle music very differently, shifting dramatically towards power metal, and would consequently gain a solid reputation in Europe.

After releasing a few succesful albums in the late 90s and early 2000s, a series of line-up changes siginificantly reduced the band's activities. They are however still active, and have "entered the studio (in March of 2006) to record the long awaited successor from Of Human Bondage."

The band's first two albums are now some of the rarest Metal collectibles in the world. They were reissued unofficially in very limited quantities in late 2002-2003. The reissues have no label or copyright info and have two bonus tracks each.

Dirk Assmuth's sister Anja plays drums in power metal band called Duke.
