Ghostface Killah (right) has been on a prolific run, both with Wu-Tang Clan and under his own steam. The rapper also has a fondness for collaborations, so it's no surprise to see him hooking up with the adventurous Toronto jazz trip BadBadNotGood. What we get from this union between like-minded conspirators is an album that twists and turns with great intent and colour. BBNG have the musical muscle and fibre to cast more than mere jazz shades and shadows, thus lending Sour Soul width and depth, from cinematic signatures to more expansive soul-laced landscapes. Meanwhile, Ghostface and a gallery of cohorts (DOOM on Ray Gun, Danny Brown on Six Degrees, former Slum Village rhymer Elhzi on the excellent Gunshowers) demonstrate storytelling gumption and craftsmanship. More GoodGoodNot Bad than the name suggests. badbadnotgood.com
