There are multiple bands known by the name Dissection, originating from various countries and representing different styles within the metal genre: 1. Dissection was a Swedish extreme metal band formed in 1989 in Strömstad by guitarist, vocalist, and primary songwriter Jon Nödtveidt and bassist Peter Palmdahl. The band released two influential albums, "The Somberlain" (1993) and "Storm of the Light's Bane" (1995), before disbanding in 1997 following Nödtveidt's imprisonment for complicity in a murder. After his release, Nödtveidt reformed Dissection in 2004 with new members who shared his dedication to the band's Satanic philosophy. They released a third album, "Reinkaos", in 2006 and disbanded shortly afterward. In August 2006, Nödtveidt died by suicide. Dissection is widely regarded as a significant influence on the development of Swedish black and death metal, especially through their early albums, which are sometimes associated with the Gothenburg scene. https://en.wikipedia.org/wiki/Dissection_(band) 2.
