Rumours have been going round for a couple of days, now it's official:
Dimmu Borgir's management company has confirmed that Jan Axel Blomberg (a.k.a. Hellhammer of Mayhem) will play on the next Dimmu Borgir CD as a
session drummer. The Norwegian symphonic black metallers had previously
utilized the services of Nile's Tony Laureano and Reno Kiilerich as touring members following the departure
of Nick Barker in early 2004.

Dimmu Borgir recently announced plans to re-record their second album, "Stormblåst" later in the year.
