The Alchemist and Oh No, respected and accomplished MCs and producers in their own right, weren't acquainted until they met at a show headlined by Dilated Peoples member and mutual friend, Evidence. Inspired, Al contacted Oh No and proposed a collaborative project. The creative sparring continued, and they began to refer to the work as Gangrene. As the project began to flesh itself out organically over the course of these exchanges, each artists relished the opportunity to best his cohort with the most profoundly disturbing, cut-throat concoction he could muster, be it a threatening stanza or traumatic instrumental.
Three years after the creative mutagen was introduced, The Alchemist and Oh No stand upon a seething heap of rugged de-compositions to be released as an album titled Gutter Water on Decon. Together as Gangrene they present a dense canvas from which verses by guests Guilty Simpson, Planet Asia, Raekwon, Evidence, MED, Twins Gambino, Fashawn and Roc-C leap into action alongside rhymes of their own. Oh No explains, 'Our sounds are really raw, gritty. It just worked.'
