The decadent techno ball, which has been heralded by everyone from i-D to the Evening Standard and has hosted showcases from labels like Mobilee, Saved and Great Stuff, kicks off their second secret roof party with great guests Heidi (Get Physical) and Lee Curtiss in charge of the deep house, unorthodox techno and groove-addicted electronic rhythms for their fun-lovin', mid-20s crowd. And today also doubles as their second birthday – hurrah!
