"The Lost Dubs" features five tracks that essentially never saw the light of day, but they were unmissable bangers during BAR9s live sets. They decided to release these tracks, along with uploading their entire back catalog one track each day to their YouTube channel, to show their contribution to the newcomers to the scene. The steady, melodious drive of "Untitled" and the layered intensity of "Pussyhole VIP" illustrate BAR9s impact on the evolution of dubstep. "Sorrow" in particular has long been a fan favorite, and now the track is finally available to the legions of their fans.
