Overview:"It must schwing!" was the motto of Alfred Lion and Francis Wolff, two German Jewish immigrants who in 1939 set up Blue Note Records, the jazz label that was home to such greats as Miles Davis, John Coltrane, Herbie Hancock, Thelonious Monk, Art Blakey, Dexter Gordon and Sonny Rollins. Blue Note, the most successful movie ever made about jazz, is a testimony to the passion and vision of these two men and certainly swings like the propulsive sounds that made their label so famous.
