On Jazz Fest’s final morning, the Dynamic Smooth Family, the Leviticus Gospel Singers, and the Golden Wings, three old soulful men, performed moving sets.

At the Economy Hall tent, the Trémé band, attired in crisp white shirts and those shiny-billed marching-band caps, began slowly occupying the stage, altogether ten strong, maximum strength for this big-time-concert/family-reunion performance. David Torkanowsky, a multi-threat pianist, jumped in behind the keyboard of the baby grand sitting onstage. Anchored by Benny Jones on snare drum, and 75-year-old Uncle Lionel Batiste on bass drum, the band’s front man these days is Glen Andrews, a young trombonist from the ubiquitous Andrews family.
