“We challenged producer Starkey (fresh over from Philadelphia) to build us a track from scratch – using samples supplied by Radio 1 DJs, dubstep artists and listeners – and put it together during a live show broadcast from BBC Maida Vale. He was joined by vocalist Anneka and percussionist Reso to build the ultimate dubstep track, all within the confines of a two hour show. Download the results below and check out the pics as the track unfolds.” – Mary Anne Hobbs
