Have seen them (REO) so many times I can't count. They are one of those bands that just plain rock live but not so much in the studio. Kind of like Cheap Trick! I am listening once again to Joe Bonamassa and Beth Hart.
Man, I saw Cheap Trick and it was 2 minutes into the first song before I could even recognize it. I dont know WTF was going on, but Rick was ~3 beats ahead of everyone else and just kept playing, they never caught up.
