Problem: this rocks they are right now one of the best bands out. Mirror Spirit is one of the best songs to come out in a long time. The only band out that is better then these guys right now is silvertide, and possibly Rose Hill Drive. Sounds like classic 70's 60's rock and roll. The singer has a great voice, I believe his name is Eric Shea and there lead guitarist is a girl but she can really play. Expect to see these guys again because this completly rocks out.
