Spektra was what Mathias Lodmalm was toying around with after the collapse of Sundown around the turn of the millennium. It was a pretty natural progression from the last Sundown album Glimmer, featuring more straight forward beats and no guitars.
Around 2003 Spektra morphed into Domain ID which was a slower kind of dub electronica.
Sometimes spelled Sp3(tra.
