THe Prodigy's festival at Milton Keynes, it turned into the best rave ever, great DJing sets and every support band was awesome (Does it Offend You, Yeah!?, Chase & Status, Enter Shikari and Pendulum),which are all 100% worth seeing alone anyway.

and this just gives some perspective of the awesome venue, but we were much closer in the front pit.
