I just recently saw coheed and cambria live and i have to say i was quite impressed. I've been to a few shows and they have to be right up there. Here's a list of my favorites 1. Atreyu 2. As i Lay Dying 3. Tool 4. Parkway Drive 5. Coheed and Cambria 6. Thrice 7. Korn (show i was at was in guiness book of world records) 8. Deftones 9. Teen Idols 10. Rise Against
i heard u2 was really good from a lot of different people. I'm not exactly a huge fan, but i heard they put on a great show.
Foo Fighters were ****ing insane. Easily, the greatest concert I've seen. Staind was right up there as my best, until I saw the Foo.
Incubus was ****ing amazing live, as well. For me though, not better than Staind and definitely not better than the Foo.
saw Matt Good acoustic live awesome and hes hilarious, comedy show + music show in one equals awesome
These annoying girls I used to know said Tool was great live. I wish I could have seen AiC or Pearl Jam live while they were in their prime. Soundgarden's early material is my favorite stuff to listen to (before they got popular), but it's hard for Cornell to sing like that in person (definitely not in 2008). He's had his "live" moments though.
My favorite live act has probably been Fuel or 3 Doors Down. Staind is damn good though too, and Hurt has to be right up there.
Either Sigur Ros or Oucho Sparks. The first because they put on a truly atmospheric performance while the second puts on a full stage show complete with costumes, acting; the whole sha-bang.
