IHSAHN to support OPETH on Norwegian tour Wed, 17 Dec 2008
Mnemosyne Productions are happy to announce that IHSAHN will support OPETH on their upcoming Norwegian live performances arranged by Rikskonsertene/Statnett.
Ihsahn had this to say about the live dates.
"I've been getting quite a few live-offers for my solo stuff, but haven't found time to prioritize this until now. I feel this is an opportunity to try out the material live on my home-ground and to travel with a great band like Opeth while doing it."
