Did you hear about Black Butter's 5th Birthday? It was a party that's already steeped in legend. The London-based dance music label sold out Electric Brixton way in advance despite having a secret lineup that was left unannounced until the night of the event. It exceeded everyone's expectations. And now they're taking the night to East London. Apart from the epic My Nu Leng, it's all hush-hush so we can't reveal the other eight acts in the lineup – but having played host to the likes of Rudimental, Kidnap Kid, Gorgon City and many more in the past, we can guarantee that it's going to be a night of quality music with the same great party atmosphere. So get excited – we'll see you on the dancefloor. Doors open at 9pm; party till 3am. Over 18s only. Valid ID required.
