The Danish / Swedish collaboration THORIUM boasts no less than three guitarists with bass duties reportedly delegated out to whichever one is the most drunk at the time. Jonas Lindblood (Linblad) has credits with TAETRE whilst drummer Jesper Frost is known from INIQUITY. The band produced an outstanding Black Death Metal record but fell foul of their record company Diehard who relinquished the band's contract due to apparent Nazi lyrics. The situation was a huge misunderstanding and Diehard resigned the group.

Vocalist Michael H. Anderson, guitarists Morten Ryberg and Allan Tvelebakk are all erstwhile members of WITHERING SURFACE. Ryberg, a veteran of cult act ARISE, also plays with INFERNAL TORMENT.

The 2002 album 'Unleashing The Demons' closed out with a cover version of CANCER's 'Cancer Fucking Cancer'. Jesper Frost joined melodic Death Metal act ECITON in early 2005. That August THORIUM cut a three track demo at Berno Studios in in Malmö. 2005 saw Frost operating with DOWNLORD, the band led by BOLT THROWER and BENEDICTION singer Dave Ingram.
