Jazz on a Summer's Day is a priceless record of the 1958 Jazz Festival at Newport, Rhode Island. It just doesn't get better than this. We see Louis Armstrong, Mahalia Jackson, Dinah Washington, Chuck Berry, Thelonious Monk, Gerry Mulligan, George Shearing, Jack Teagarden, Sonny Stitt, Chico Hamilton, Anita O'Day and Big Maybelle, so we'd stay glued to the screen even if the film was poorly made. But it isn't: director Bert Stern not only does a masterful job of filming these imperishable greats at their very best, but he manages to make the whole enterprise fascinatingly fluid and thoroughly cinematic. Even non-jazz buffs will be exhilarated by Jazz on a Summer's Day.
