We don’t know much about Sully. Most people don’t. Discogs claims he’s one half of drum’n'bass duo Spectrasoul, but this might not be true [edit - it's definitely not true].
Anyone with half an interest in swinging, percussive garage and gorgeous, enveloping melodies should have a full interest in Sully’s FACT mix – it features new, untitled productions from your man, plus fresh material from Kowton, Sbtrkt and more. Full tracklist on page two.
