This has been a good year for music discovery, mostly through my Spotify subscription.
Nightwish concert. That led me to track down the work of Delain, who had been one of the opening acts. With input like that, Spotify's discovery lists found several other similar artists. My favorites to this point are Amaranthe, We Are the Catalyst, and The Murder of My Sweet.
It's pretty easy to see why all of these bands ended up on the same playlists, when you consider the similarities. All have female vocalists, and most have lots of songs with alternating male/female vocal parts. Lots of classical influences in the music, implemented with metal's heavy guitar lines and driving beats.
All those bands also happen to all be from Nordic countries. Something in the water up there produces symphonic metal, I guess. At first I thought that would mean opportunities for live music would be pretty rare, but there are actually quite a few tour dates in the US. Judging from the show lists that I've glanced over on their websites, most seem to spend about a third of their tour time here. I've got my eye on a few dates next year, mainly in the Chicago area.
I'm pretty sure I've barely scratched the surface of the genre. So far I really haven't looked beyond whatever recommendations Spotify tosses at me. Even so, I've got an awful lot of music that's new to me to listen to.
