100 Days, 100 Nights is a complete throwback to late 60s and early 70s R^B with no reservations. You can definitely hear the Winehouse&Ronson connection *Ronson produced Amy-s @Back to Black@(. The baritone sax is the signature instrument here and I love it. Sharon Jones sings with such conviction, which luckily is not lost through overproduction like some other recent throwback soul recordings. This is obviously due to the band-s insistence of recording on vintage, analog equipment. A must have!
