This intriguing event – organised as part of the London leg of the Red Bull Music Academy UK Tour – pays tribte to the era of illegal raves and free parties, where the only way of finding out where the action was taking place was to ring or text a special number (usually found on makeshift flyers advertising the party or through covert contacts). In truly authentic rave style, it's a free event, and the location and line-up will only be revealed on the day.
In keeping with the hush hush vibe, the finer details have yet to be revealed, but we're guessing it may well involve punters texting or ringing a given number on the day. Prepare for a lot of fun and partying like it's 1995 all over again.
