Here are some that no one asks:
Do you have any plans to colaborate with Steven Wilson, and Mike Portnoy?
How much work is it to add in the keyboards during a live show? Older songs don't have them but they are added.
Do you ever plan to go even further out of the metal context, even if its just for one song? Jazz? Atmospheric? Emo? (
)
Will we see any new Opeth tunings on future albums? (Ghost Reveries is dropped if I am correct)
Will Mikael be working on any new comedic material during the next break?
Howcome Per is insane during live performances?
Have you heard the piano interpretation of Damnation that was created by a german fan? (tell them they should check it out)
Plenty of more... just can't think of any right now.
