I can recommend you some Finnish bands. You propably(/maybe) already know HIM or the Rasmus...or Hanoi Rocks
ANyway here are some names: Suburban Tribe, Flaming sideburns, Tiktak, Killer, Negative, Smak.....the list go on and on, but I just woke up sometime ago and I'm a bit sleepy, I can't come up with any other bands... I should listen to radio more often...
