I am listening to the most recent Nightwish CD called "Dark Passion Play".
I first became aware of this group when I was playing a MMORPG called Anarchy Online and was listening to the in-game radio broadcast. They played "Ghost Love Score" off of their "Once" CD and it was exactly the kind of music I had always hoped was out there so I picked up the CD and liked every song on it.
Shortly after this the band fired their lead singer and I eventually figured they were finished and stopped visiting their website.
Literally, two or three weeks ago while surfing the web I thought about them, went to their website and found out they had a new lead singer a new album and were touring Canada. It turned out they were in Edmonton that night and would be in Calgary the next, the only problem was the show was sold out and I had no babysitting anyways. :-(
It isn't for everybody, but here are some videos

Note, the Islander isn't a typical track though the next two are (the last two are older songs with their former lead singer).
