i saw SFA just before phantom power was released. maybe i just caught a bad show, they seemed a bit flatter than i anticipated. they look better on their dvd though. gruff did some songs by himself on the acoustic, some in welsh. definitely familiarize yourself with their older material as they went back for that as much as anything. and definitely get to know their awesome tune, 'the man don't give a fuck'. they closed with that and it was beautiful.
