THE ORB  Thirty-five years since Alex Paterson lit the multi-coloured touchpaper on The Orb’s interstellar space odyssey, he continues to swerve, becoming his own tribute act by never standing still and preparing a cluster of fresh new projects.   LEFTFIELD (DJ SET)  Leftfield (originally comprising Neil Barnes and Paul Daley), have been at the cutting edge of dance music since the 1990s, releasing albums that have become some of the most influential electronic records of all time around the world with their debut LP Leftism being widely regarded as one of the most boundary-pushing electronic LPs ever released.
