Difficult Decisions

Opeth > Sigur Ros

But... you should go see Sigur Ros just because you've Opeth many times already and will most likely get to see them again before you get to see Sigur Ros again.
 
I've heard it and yes, it's VERY good.

well of course for me....Opeth...Of course...John raves about Sigur Ros I am sure this is a difficult decision for him....Oh what a nice Birthday present this would/could/should be

Pssh... this is way after your birthday.

Edit: I've seen Opeth 5 times. Sigur Ros.
