Well, it's 2 1/2 hrs solo without any long jams or stage antics to carry you. Solo work is very demanding. Nothing to hide your mistakes. No doubt, it's work.-Richie
Wow, that's hardcore. You must really want it. I'll bet it's a cracking gig though.
I've never played for longer than 1hr and even then I'm exhausted. The thing for me is the nervous energy of being there - if it was in my garage I could play all night and not notice it.
