Robert Nighthawk was one of the most influential blues guitarists of the post war period, a stature he achieved without the benefit of many hit records. His song "Sweet Black Angel Blues" became a blues standard when B. B. King covered it as "Sweet Little Angel" and B. B. went on to do the same with "Crying Won't Help You". Across the 23 tracks presented here are top blues musicians such as, Roosevelt Sykes, Sunnyland Slim, Willie Dixon, Brownie McGhee and Pinetop Perkins. Robert Nighthawk was an important and very underappreciated bluesman whose evocative slide guitar influenced a remarkable number of musicians who followed in his wake.
