Subway to Sally
 

Subway to Sally formed around 1992 and are a popular medieval/rock/electronic later even a little metal crossover band. They started as a pure folk band and developed from there. Their lyrics are mostly german, and are very poetic and beautiful.. well if you understand german of course, lol :D

Here a few examples:

Subway to Sally - Kleid aus Rosen (Dress made out of Roses)

I've heard their debut album, and I think it's pretty cool.

You should give the other albums a try, too.
Subway to Sally evolved a lot in their time as a band :)
