In February of 1999, Ken suffered a near-fatal brain hemorrhage, leaving him in a coma for over 10 months.

As a result, he is not taking part in Carcass\' current reunion tour. The group recruited Arch Enemy\'s Daniel Erlandsson to fill in. But Ken is traveling with the band whenever possible and has made brief appearances - including some drum solos - at select shows.

The 22nd edition of Wâldrock takes places in Burgum, Friesland (the northern part of the Netherlands) on Saturday June 13, 2009.

Tickets pre-sale will start on January 13, 2009.
