Ghostface Killah is not only one of the top emcees of all time but he's also undoubtedly one of the hardest working men in hip-hop. Since last month he has released his excellent solo album "36 Seasons", appeared on roughly half the tracks of Wu-Tang Clan's reunion LP, and prepared the second collaboration with Sheek Louch and a host of guest emcees from both camps under the Wu Block banner (that "Hidden Gems" album should've dropped this Tuesday but seems to have been pushed back - what's the deal?). As if that wasn't enough Tony Starks is already getting ready to drop yet another full-length project. Following his storytelling over live instrumentation projects with Adrian Younge and The Revelations, respectively, Starks now taps Canadian jazz trio BadBadNotGood to provide the backdrops. I'm not too familiar with the group save for some scattered tracks (including "Rivers of Blood" with Ghost, G Rap and Raekwon which they co-produced) and an interview in Bonafide, but what little I've heard sounds good and Ghost is notorious for picking ill sounds to rhyme over. "Sour Soul" is out via LEX Records on February 24, is completely produced by BBNG in collaboration with Frank Dukes, and sports guest features from Danny Brown, DOOM, eLzhi and Tree.
