V/Vm (James Kirby) is a one-man glitch/mash-up/noise band from the UK.
He is known to ignore copyright laws and regularly mashes up classic gems, usually making them more enjoyable (or painful).
He runs a record label through which he publishes his large output and that of other fellow artists (Jansky Noise, Toecutter etc.).
Concerts usually feature him wearing a pig mask and a bird costume and a lot of rolling around on the floor, bleeding and ecstatic fans on the stage.
