West Coast producer/emcees The Alchemist and Oh No will release their second psych-rap full length as Gangrene on January 24th on Decon. The new record, Vodka & Ayahausca, is a follow-up to their gritty Decon debut Gutter Water. Al & Oh again split their time between helming psychedelic beats and spitting tripped-out rhymes. While Ayahuasca (a natural hallucinogenic brew, containing DMT) may not be a term familiar to the palette of the average rap consumer, Gangrene is about to change all that. Vodka & Ayahausca boasts choice collabs from Kool G Rap, Prodigy (of Mobb Deep), dilated ally Evidence, and Greneberg EP collaborator Roc Marciano, who laces the suggestive “Drink Up”, a welcome addition to the kaleidoscopic head-trip. The first single from Vodka & Ayahuasca ”Dump Truck” ft. Prodigy will be available worldwide on November 21st, 2011.
