This two-disc compilation contains a pair of DJ mixes of some of the best released and unreleased dubstep tracks of the past few years. The first, mixed by Youngsta, gives the music a historical context by featuring the slow, booming, bass-wobbling sound (from artists like Loefah, Distance, Hijack, and Benga) associated with scenes largely based in London and Bristol. The superior second mix by Geeneus looks forward to the future of dub, inserting genre-busting selections by Shackleton, TRG (as remixed by Martyn), The Bug, Kode 9, 2562, Mala, Skream, and Burial, the breakout star who still rules with his haunting, indefinable talent.
