for future reference wait for kalmah to get a tour in europe before you even ask if they will come to america, because they most likey wont come for a while its the sad sad truth
it's not really up to them where they go, it's up to their record company and it depends how many CDs are purchased in the US. that would be extreamly killer if they toured in america though for the upcoming album!
few good bands play in n. america
The black dahlia murder
Between the buried and me
The Red Chord
(opinion)
and a few others but thats not even on the same level as kalmah.
