We went to see this last night. It was fantastic and I'm amazed at how people can just play like that. I can't remember the last time I saw someone play like this, live, and it makes me want more. That and it makes me want to play more myself. I've been doing that, of late, playing more. It seems to be paying off.
Anyway. The competition runs for another 2 weeks and it starts moving into more demanding things, not that this isn't demanding. I doubt I'll get to go again, but I definitely say it's worth it.
