The standard bearers of grime, Butterz, return to Room One once again this January, bringing with them another one of their heroes, Kano. After making a fleeting appearance at one of their shows here last year, he’s returning to headline and will do so atop a bill that features Elijah & Skilliam, Swindle, the influential DJ, Spyro and Gobstopper boss, Mr Mitch (who’s still fresh from the release of his debut album, Parallel Memories, on Planet Mu).
