'I wouldn't say I suffer from synaesthesia, but I can hear a sound and write a colour down,' said producer Joker to The Guardian in 2009. Perhaps that explains how the Bristol-based beatmaker came to be associated with a dubstep variant known simply as 'purple'. Whatever you want to call it, Joker's music bears a far lighter touch than many of his dubstep peers, replete with 8-bit melodies, futurist synths and the kind of viscous grooves that you can imagine going down well at an LA pool party. As he prepares to release debut album The Vision on esteemed British indie label 4AD later this month, he'll be scooting through Tokyo to give the locals a bit of purple goodness. Local heavyweights O.N.O, Kuranaka 1945, Goth-Trad and Cashy flesh out the bill.
