Alex English and GBH are back with their big electronic-dance-music bash, held in Webster Hall’s massive Grand Ballroom. This week, the team brings in West London’s Caspa, who mixed an excellent compilation on the renowned FabricLive series a few years back with then-partner Rusko, and in the process helped take dubstep out of basements and into main rooms. (Whether that's good or bad is a matter of opinion.) Opening sets from Kill Paris and Mayhem x Antiserum add a bit more bass to the bash.
