Zero Sum is a track that has become a stone cold classic. Its timeless sound and feel, is up there with tracks that form the golden era of Jungle. Available for the first time on 10inch vinyl, Sully has worked his magic on this release. There is also a refix on the other side from one of the golden era s classic duos Dem 2 Ruff. Their Refix keeps the vibes of the original but in true Dem 2 Ruff fashion. It comes to slaughter your speakers, be warned its ruff but still nice too.
