Jack Adams is Mumdance; a DJ and producer whose mashed up style uses many an unsuspecting genre to add to the ruff-ness of his mix.
Dubstep, bassline, fidget house, electro, niche, techno, jungle and so on are all immortalized in his sets.
Diplo heard Jack's baille-grime remix of the Black Lip's 'Vendi Vendi Vendi' and commissioned him to remix Santogold and El Guincho. Ninja Tune have jumped on the bandwagon, getting him to remix Pop Levi. Loads of his bootlegs have been caned by Radio One and he's generally accepted to be fucking awesome.
Bass-driven badness.
