**Love dancing to hedonistic, high‑energy dance tunes?** Then join me on a proper dance floor for our 3rd edition of an euphoric, high‑octane dance music night with one of the finest French Swiss **dance‑music DJs and Producers** out there dropin phenomenal uplifting spiritual, hypnotic melodic grooves for us to lose ourselves to in one of the most iconic venues in London’s clubland — **KOKO** Camden, in the home of music. Collectively - their music has amassed over 18 million streams. Expect a proper dance music club‑night experience with inspiring immersive lightshows / lasers for our bodies to sync in harmony to as with gyrate to the **rhythms** of the night. Obvs there will be no boring mainstream "touristy" pop rubbish but proper dance music - think - ecstasy inducing tunes you'd dance to at other music clubs like Lightbox, Egg, Bagleys, Ministry, Moondance, Fabric, Paradise, Studio 54 (Brooklyn) spun by global DJs renowed in these genres. We'll join up to 1,500 other fellow cool young trendy music lovers for a night of blissful musical tranquility, Average age range will be 18 to 35ish heavily skewed toward 20s men. **Free Tickets limited.** Sorry but if you don't love both uplifting loud music and dancing to it - please don't rsvp and deprive genuine musical dancers an extremely rare free place! And honestly, if you're only gonna stay for less than a couple of hours there's probably no point in coming. You don't need to stay till 5am like last time but as per most proper clubs - the real revellers don't usually arrive untill 1ish and the main DJ / music sets don't even kick off till 12 so it's would be waste of a free ticket that you'd normally pay up to £70 quid for! Oh & please don't ask me about 3,4-methylenedioxymethamphetamine - I'm not a biochemist - try your local Boots! **=== Time To Make The Floor Burn But Early ===** The only downside is we have to get in there before 11pm else regular door charge tickets will be about £45-80 quid. If you wanna pay for full price on door/ pre-buy and meet us in there later that's cool too as 11pm is understandably way too early to go a club - we can sort out the details later. DM me for the free ticket link. We'll meet beforehand somewhere quieter for pre-drinks, intros, banter and obviously music chats about our previous rave escapades, our fav tunes, and non-music related banter. As Koko gets packed by 2am (1500 standing dancing cap) and we have restricted free tickets - to avoid losing people - a small group size will be optimal for dancing and socialising so limiting RSVPs. Obviously you can dance with the other random ravellers as pour in after the pubs shut. Will update with nearby super cheap pre-drinks Camden venue in the location and comments so keep an ear out Lucas The Raver
