Sour Soul is a collaborative studio album from Canadian jazz instrumental hip hop band BadBadNotGood and Wu-Tang Clan member Ghostface Killah.

A majority of tracks were recorded in Thomas Brenneck's Dunham Sound Studios in Williamsburg, Brooklyn with contributors from New York soul revival scene including sessions musicians from The Budos Band and Daptone Records engineer Wayne Gordon.

Other recording sessions took place in Frank Dukes' Kingsway Studios with contributions from Toronto artists River Tiber and David Lewis.

In a mixed review for Exclaim!, Eric Zaworski noted that the record "hurriedly finishes without giving its concepts enough time to bloom," further explaining that "the production is top-notch, but Ghost rarely shifts into uncharted lyrical territory, holding back Sour Soul's otherwise consistent production.

"[10] In an extremely positive review, giving the album a score of 9 out of 10, Sam Moore wrote for Drowned in Sound that "Sour Soul is sublime."
