“I think it’s rare to find an improviser that all goes and nothing has to go at all,” says Ambrose Akinmusire of Mary Halvorson.

Sheila Jordan was one of the first vocalists to fully internalize the language of bebop and transform Charlie Parker’s pioneering musical ideas into a vocal art form all her own.

Jaki Byard teaching at the Mark Levine Workshop in 1991. “He could crack jokes, but when he sat down, it was serious fun,” says pianist Fred Hersch, a former student.

The critics choice for Historical Album of the Year is At The Deer Head Inn: The Complete Recordings.

“I feel like most of my music is more classical music than jazz,” Adam O’Farrill says. It’s both and more.

“We have figured out our show, and people seem to be really connecting with it,” Emmet Cohen says of his band’s current tour, a tribute to Miles Davis and John Coltrane. “The audiences are large and exuberant. It feels like we’re doing what we’re meant to be doing.”

On the festival’s final night came a duo composed of two one-offs — guitarist Julian Lage and bassist Christian McBride.
