Passport is a bebop tune by Charlie Parker that actually refers to two distinct tunes with the same name. Passport Blues is a blues in C recorded on May 5, 1949 with Parker’s All-Stars, while Passport Rhythm Changes is a second take built on the rhythm changes progression from the same session. Mastering notes later highlighted the mix-up, with Phil Schaap explaining that two different tunes were labeled Passport in the archives. Both takes come from Parker’s 1949 studio work with Kenny Dorham, Al Haig, Tommy Potter and Max Roach, and they have been issued on later compilations such as The Complete Charlie Parker Intégrale Vol. 6: Passport (1949). The rhythm changes version is the one most widely circulated in sources like Omnibook and has been explored by later players such as Joe Henderson, while the blues version remains a rarer find. Year of recording: 1949; Genre: bebop jazz; Original artist: Charlie Parker.
