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.
