There are at least two bands, who share the name "Crematory". 1) A German Death Metal (early), Gothic Metal band formed in Mannheim, Baden-Württemberg, Germany in 1992.
The German Crematory broke up in 2001 and reformed in 2003 to release the album Revolution, a largely progressive effort which brought the band into more accessible/techno-metal territory than ever before.
Their sound has often been compared to early-Sentenced, Fear Factory, and Dark Tranquillity. The band received its earliest recognition in the mid-1990s by touring with My Dying Bride, Tiamat and Atrocity.
