Sarah Vaughan's EmArcy sides are exciting and vibrant, and show off her talents while she was making the kind of music she enjoyed the most. In The Land Of Hi-Fi adds a nice twist to the usual high-standards of her EmArcy recordings, in that one of the featured players is a young Cannonball Adderley. According to the liner notes (where he is still referred to as the Florida Flash), he "flew north with alto under arm especially to take part on these sides."
