The Vaults in Waterloo form a labyrinthine underground world; Vault Festival’s making the most of all that interesting space with six weeks of sold-out shows and unusual events. Come out and celebrate with this ace bit of partying, designed to get you dancing and making merry into the early hours. This is a straight-up night of pure fun, and we’ve managed to wangle some tickets for next-to-nothing. So raise your glasses to Vault 2014: it’s a good ’un. General admission. Over 18s only.
