Yeah, Hollentorn, Meshuggah, Napalm Death, Children of Bodom and In Flames are my picks.
SB gives me hope for this fest because it started out in much the same way about 5 years ago, only being a showcase for unsigned bands, now its getting soem of the most massive names in underground metal to play there (The Gathering and Dimmu Borgir played last year I believe) so give BS a couple of years and I'm sure it can do even better simply cos the demand for underground metal is here but few bands play here because there aren't that many places to play
