THere are at least 2 Bands with this Name.

1: Tormentor (Hungary)
It was brought to existence over a decade ago, more precisely in the beginning of 1987.
The band has done two demos, namely: “The 7th Day of Doom” and “Anno Domini”. Both were recorded in 1988. “Anno Domini” was also recorded as an album.

Tormentor’s vocalist Attila Csihar, who’s now quite famous for his insane and inhuman way of using his voice, was later asked to do the vocals on Mayhem’s then long awaited “De Mysteriis Dom Sathanas” album. Tormentor was also offered a deal on Euronymous’ cult label Deathlike Silence Productions, but due to a lot of difficulties it was delayed and for obvious reasons the deal between Tormentor and DSP never happened in the end.

NAP managed after a while to get hold of the original DAT master to “Anno Domini”, and was kindly granted the exclusive rights for the recording by Mr. Csihar.

NAP put out the “Anno Domini” album in 1995. It was also put out on limited edition LP (in co-operation with Head Not Found) and on limited edition picture disc (in co-operation with American label The Ajna Offensive). The band itself actually split up in 1991, but was later reformed.

2: Tormentor (Germany), nowadays known as Kreator.
