Part of Las Vegas' mega-complex Wynn — the building containing Surrender/Encore Beach Club — XS is so big it requires its own entry in this poll.

With capacity for 5000 and a giant golden chandelier hanging from its elephantine main room, the phonetic letters of its title spell out exactly what's in store from this massive digital mind-fuck, equipped with all the flashing screens, CO2 cannons and brostep fist-pumping you'd expect from the entertainment capital of the world.

Those after subtle 4/4s and deep hypnotic techno, look away now. XS played host to Avicii, Steve Aoki and Tiestö in 2012, while (All Gone) Pete Tong presented a rare 125bpm treat with Eats Everything last November.
