Cult of Luna is a Swedish post-metal band from Umeå. They formed from the remnants of a Umeå hardcore punk band called Eclipse in 1998. They slowly garnered critical appreciation and underground popularity with early releases Cult of Luna (2001) and The Beyond (2003); however, it is 2004's Salvation that can be considered their 'breakthrough' release. This was followed by Somewhere Along the Highway in 2006, another largely well-received album.
In August 2006, the band released a remake of "Marching to the Heartbeats" from Somewhere Along the Highway entitled "Heartbeats" solely on the internet community MySpace. The song was available for download for a few days and was later removed. The point was to see if the song would be kept alive by file sharing, and was also apparently a statement against the conservative music industry, said keyboardist Anders Teglund in an interview.
In 2008 the band released its fifth album, Eternal Kingdom. It was released in Europe on June 16, followed by its release in the United States on July 8.
