I saw Katatonia open for Opeth at 2000 Milwaukee Metal Fest, where they both played an hour. It was both bands first-ever U.S. appearance. I remember Opeth opened with "White Cluster" and Katatonia played 5 songs from Discouraged Ones, 4 from Tonight's Decision, and Endtime. And Daniel looked like a 12 year old.
I also remember Opeth opening for Nevermore like 4 years ago on a U.S. tour, and this fall, Nevermore are opening for Opeth! How's that for a slap in the face you horrible power metal faggots?!
