COLDWORKER was a Swedish death/grind band. The band came to existence about a year after Nasum tragically called it the quits. Drummer Anders Jakobson started looking for members for a new grinding band. After posting in his blog at Nasum.com, Anders Bertilsson (of Ruin) - vague acquaintance to Jakobson - offered to play the guitar in the band. At the same time bass player Oskar Pålsson (of Relentless) was looking for a session drummer for a possible solo demo. He asked Jakobson who informed him about the new grinding band plans and the two ideas were quickly merged into one.
