What to expect

Expect a charged, committed crowd. Arriving on the early side buys you the good spots. Energy is the product. Pace yourself; the peak comes later than you think.

The essentials

Pricing sits at the premium end, and the event runs Fri 06:00. You'll find it at Old Billingsgate, London — the surrounding blocks carry the same energy, so the night doesn't have to end at one address.
