This double LP release features one of Miles Davis final great bands: John Scofield on guitar, Bill The Other Bill Evans Evans on saxophones, flute and electric piano, Darryl Jones on bass, Al Foster on drums, and percussionist Mino Cinelu. Miles was back in amazing form (incandescent and iridescent as ever, critic Greg Tate noted), when he mounted the stage at the Theatre St-Denis during the Festival International De Jazz De Montreal in July 1983, and this revelatory performance has been lovingly mixed and mastered for its first ever release, on vinyl for Record Store Day 2022. (A CD will be part of the next edition of the Miles Davis Bootleg Series, focusing on the 1981-1985 period, later in the year.)

What It Is includes tracks from that years release Star People, the Marcus Miller tune Hopscotch and the song Jean-Pierre that appeared on 1982s We Want Miles. The recordings of What It Is and Thats What Happened were so well thought of by Miles that he utilized them for his 1984 release Decoy, but in heavily edited form and this release would include the first release of them in complete form. Packaged in beautiful gatefold packaging, the album features liner notes penned by the incomparable music journalist Greg Tate and represent some of his final writing.
