Oh my god how amazing was Oxegen? The rain coming down in Citien Erased and USOE was magical. And the sparkly lasers made Undisclosed so much more interesting that the stupid B-stage... What a gig!
It's too hard for me to name a single performance but from pro-shots TSP at Earl's Court was amazing and in the flesh anything from CE and Bliss any time I've seen them and Unnatural Selection, especially at Wembley, is so powerful.
