Polar AC is a compilation album by jazz trumpeter Freddie Hubbard. It was his final album released on Creed Taylor's CTI label and features performances by Hubbard, Hubert Laws, George Benson, Junior Cook, and Ron Carter. It was put together by CTI after Hubbard left the label to go to Columbia, and the tracks were recorded at different sessions, between 1971 and 1973. The album featured pieces: "People Make the World Go Round" and "Betcha, By Golly Wow", recorded both on April 12, 1972, and "Son of Sky Dive" recorded around 1973. "Polar AC" (aka "Fantasy in D" and "Ugetsu") came from First Light sessions, whilst "Naturally" was recorded during Sky Dive sessions, and both can be found on CD reissues of their respective albums.
