Thanks for the suggestions guys. I too am always on the watch for new bands. For "melodic rock" I suggest:

Dredg - El Cielo or Catch Without Arms (comes out June 21) I was really shocked when I saw that these guys were on Interscope Records. Not your every day big label band.

Blackfield - Blackfield

Porcupine Tree - In Absentia or Deadwing

Now I'm off to check out y'all's suggestions.
