Sheepey,
Gotta love the Protest the Hero, really amazing considering they made their first album while being Seniors in High School.
I'm going to Progressive Nation 08' which should be awesome, Dream Theater, Between the Buried and Me, Opeth and 3. 3 isn't really metal, its more just progressive rock, but its still got a good groove to it.
I've been enjoying Nightwish, anything Prog Metal (Alot of Opeth and Between the Buried and Me lately, which is why I'm pumped for the concert), In Flames, At the Gates and just a touch of August Burns Red (Im a drummer and I definitely appreciate the awesome breakdowns)
I also really enjoy the band I Am Ghost. They are some strange blend of Pipe Organs, Hardcore (the style), Metal, Violins and Gregorian Chant. Very interesting.
