It’s a busy night in London. Katatonia headlining the Koko, performing Last Fair Deal Gone Down in its entirety and filming for a new DVD. Marty Friedman is at the Camden Underworld, widdling away and giving the guitar geeks all the musical porn they need to fretwank to. New York bruisers Emmure are headlining the Relentless Garage, providing the perfect downtuned soundtrack for some brutal pit action and dance moves people choose to forget when they wake up. DETAG.
