Otis Spann's Chicago Blues (also released as Nobody Knows My Troubles) is an album by blues pianist and vocalist Otis Spann recorded in Chicago at two sessions in 1965 and released by the Testament label.[1][2]
AllMusic reviewer Richie Unterberger stated "divided between solo piano performances and pieces with a full band ... The variation in approach means that this isn't the most consistent Spann album, and the material and performances don't rank among his best either, although they're reasonably solid".[3]
