Andi ChorleyProof Positive is a 1964 album by American jazz trombonist J. J. Johnson featuring performances recorded in 1964 for the Impulse! label.
The Allmusic review by Scott Yanow awarded the album 4½ stars stating "This CD reissue finds trombonist J.J. Johnson in prime form. In fact, his melancholy minor-toned explorations often recall Miles Davis, whose group he had played with the year before". - Wikipedia
