Oh I forgot to add, in addition to his playing, there was a lady with an overhead projector doing a really simplistic (yet kind of cool) shadow puppet theatre type of thing using cellophane sheets with drawings on them. Great show, he was opening for Bloc Party - who were also good, but not amazing.
I saw Final Fantasy live, it absolutely blew my mind. It's just the one guy on stage with his violin and some footpedals that allow him to sample and loop his violin. Amazing how the one guy could just create such full, realized songs all on his lonesome. See him play if you can!
