Not for the feint-hearted, this one. Berlin's primary techno label, Ostgut Ton, goes head-to-head with Modeselektor's 50 Weapons imprint, resulting in a collision of warehouse-melting proportions. The heavyweight lineup inclues Marcel Fengler, Barker & Baumecker live, and Function from Ostgut Ton, and repping 50W are techno warrior Shed, footwork/bass mangler Addison Groove and Benjamin Damage. Perhaps the most fearsome prospect of all is a set from special guest Rob Hood, the man who pioneered the stark, obscenely raw techno sound still worshipped and rinsed by producers today. Bring your four-to-the-floor crash helmets for this one.
