Zapback returns after a short break to celebrate its second anniversary with its biggest line-up to date.

The promoters are also promising to transform the venue with a massive sound installation, a laser-light and VJ show, UV decor and extra air-conditioning.

The DJs on display read like a who's who of the hardcore scene. Slipmatt is back from Ibiza to play an exclusive old school set while Altern 8 make a welcome return to Zapback and as ever will have their dust masks and boiler suits at the ready.

DJ SS will be playing an exclusive set made up of classics from his Formation label. Brighton will also be honoured by DJ SY's first old school set in the city for many years, teaming up with his old partner in crime from the rave era, Scratchmaster Techno.

Top Buzz will be offering up an exclusive '92'95 jungle techno soundclash, while the jungle room will be hosted by Brighton jump-up crew Junglizm, with guest selectors Kenny Ken and Dr S Gachet.

The white room will be going until midday, so it won't be a night for the faint-hearted. As the promoters put it: "Dust of your old school gear and show those nu-raver types how its really done."
