There are several bands using this name: 1. Lithium was a Swedish electronic industrial band formed by Johnny Hagel(previously in bands like Tiamat and Sundown), and Carl Nilsson(previously in Moth). They released their album Cold in 2002 which met with moderate success and tours to follow, including performances at festivals like M'era Luna.
Work commenced in 2003 with a new album which was finished in 2004, but was never released due to problems with the record label, finally leading to the band being dropped altogether and disbanding shortly thereafter.
