Just to clear up the rumour - Opeth will not be playing in Greece on 17/3. At the moment Mike is busy writing the next Opeth album (make that 'albums'), and as such, the band will not be doing dates anytime soon. The possibility of going to Greece was mentioned ages ago, but that was as far as it went. Opeth never confirmed the gig so we're not sure how and/or why this information got out. Just please know that Opeth did not cancel anything.
I just spoke to Mike and he is very focused and really into what he's coming up with for the albums. It's going to be brilliant!
