Numbers 6th Birthday @ Sub Club, 3 July

It's that time of year again when the Numbers crew celebrate another year of selling out the Arches and the Sub Club, getting their faces into commercial clubbing monolith Mixmag, and generally reminding us how great their emergence was – six years ago, they were squeezed in to the back rooms of restaurants and hotels.

Their birthday parties are an excuse to splash out on the finest guests, who, as every discerning Numbers follower will know, will become the words on everyone's lips in the following months.

Berlin duo MMM, aka Eric & Fidel, are perhaps best known for Eric's project Errorsmith, who have ripped apart the Brunswick Hotel on many a Numbers night with soul-crushing electro-tech.

Shining the light for dubstep is Bristol's Gemmy and Guido. Forming the lauded Purple Trinity with former Numbers guest Joker, their names have become a guiding example for any dubstep listener. Playing together, expect more than the usual wobbly bass overload – Timbaland-esque RnB, 80s Funk and 90s G-Funk truly keep the kids dancing. [Rosie Davies]
