Thanks Surfpunk. I think you will really like Supertransatlantic. Jason Bieler(Saigon Kick) is the singer and guitar player. Pat Badger(Extreme) is the bass player. They do a cool cover of "Can't stand losing you" by the Police.
Another band you would really like is Athenaeum. It is a couple of years old. You may have already heard of them. If not, I highly recomend it. Great harmonies. The disc is called Radiance.
Big Wreck is another good band. It also came out a couple of years ago. Some cool guitar work for a modern rock band.
If you like bands along the lines of Creed, then I highly recommend a band called Doubledrive. Kickass modern hard rock. Great vocals and guitar work.

Ok, enough for now. I could go on for days......

Later,
