One of the best festivals in the UK calendar begins today, for the very last time. With the cream of the electronic crop assembled for its final showdown, Bloc promises to be a complete blowout of ridiculous proportions. The venue, Butlins in Minehead, will feature pool parties with The Egyptian Lover and pool tournaments with the legendary Steve Davis; just to give you a flavour of the antics in store. Sets will range from forward-thinking producers Slackk, Evian Christ and Holy Herndon, to techno talismans Jeff Mills, Carl Craig and Surgeon all performing amongst the festival's super-eclectic line-up. Here are ten sets that you simply cannot miss.
