Yay! I was there too! Got really really drunk afterwards at Kontiki and talked to the guy from Burst and told him that his new haircut was the "All New Burst-frilla". Nice chap.
I'm also in an opeth tribute band, from Quebec city Canada, and we are going to upload a 8 to 10 minute mix of recordings we have done now and then during our practices. The sound is very bad but I think it is quite good in person. Check this out in a few days : http://www.myspace.com/lamentationstribute
