I am a big fan of Mikael's voice on Opeth's mellower stuff like the Damnation album and songs like Still Day Beneath the Sun. So why doesn't he form a band that that focuses on the type of stuff he did on Damnation freeing up Opeth to just concentrate of the heavy stuff like the album he hinted at on the lamnetations DVD?
Maybe he could do albums only and not tour so he doesn't take too much time away from working with Opeth. He could even have Opeth's other musicians guest on the album as well as people like Steven Wilson or (gasp) Robert Fripp.
Maybe I'm being selfish ,but since everyone in Opeth agrees that Damnation was a one time thing for Opeth, I think Mikael should create an output for his mellower and proggier leanings.
