Here are a few prog rock/metal. First up, Epica.
Keeping with your time theme.
2:22 - Grace Potter & the Nocturnals
I saw her a few years ago, when she was still with The Nocturnals. If I remember the concert, she opened up for Michael Franti. Really good concert.I happened to catch Grace Potter at a small bar in New Jersey last year along with a guy named Noah Khan (And Bruce Springsteen). It was quite a night.
