Apart from Sabbath, already got the bands I care most about from this list for SRF.
In fact, of all the ones SRF doesn't (yet) have, I'd only take Saint Vitus and Sabbath.
Still, Hellfest do usually spread the quality throughout all three announcements, so the next one could well have some gems in it. Don't be surprised if COB are a headliner, though.
30/7 King Diamond
1-2/8 BiesenRock Festival
