Sour Soul is the collaborative album from Toronto jazz/hip-hop band BADBADNOTGOOD and Staten Island rap champ Ghostface Killah. Inspired by 1960s and 70s music - taking inspiration from the recording techniques and production of that era, and eschewing sampling in favour of live instrumentation, BBNG with producer Frank Dukes have created a dramatic, cinematic musical staging for Ghostface’s vivid storytelling. Sour Soul also features guest spots from MF DOOM, Elzhi (Slum Village / J Dilla), Danny Brown and prodigal new rapper Tree (Project Mayhem).
