x-mass and no mercy both become boring last years. every time the same bands.
think about : vader, marduk , cannibal corpse ,six feet under, krisiun
nothing against those bands, but always the same.
they should book bands like satyricon or pungent stench (just mention some). bands that never played on those festivals. but no gothic.
only black , death , thrash
I'm afraid tristania won't got very much time to play on the tour in september. too much bands already in this package. the best tristania gigs are the exclusive shows in the small clubs. those are my experiences.
