Dubstep, a bass-heavy, raga-based electronic genre, was becoming plodding and aggressive when Shackleton revived the micro-genre with his hypnotic World Trade Center memorial "Blood on My Hands." This compilation, which Shackleton put together with his pal Appleblim's label, includes the song (and a psychedelic remix by Ricardo Villalobos), but it goes way beyond the minimalism they're both known for, borrowing Middle Eastern and South Asian rhythms and instrumentation for a sound that's positively slinky.
