A looped vocal sample shuttles back and forth in stereo, chirping and trilling. It interrupts and defamiliarizes the sustained melody that Chloe Kaul coos over a few piano notes and a chattering beat. It also acts out the way that the lyrics have her shuttling between separation — “I never want to be the stop in your life plans” — and reunion — “never say never.” The song’s last dissonant notes don’t guarantee any outcome.

Kenny Barron and Mulgrew Miller, ‘Joy Spring’

Two jazz piano masters whose studious, tradition-grounded styles have always made them a little too easy to take for granted, Kenny Barron and Mulgrew Miller gave a smattering of rare duet performances in Europe in the years before Miller’s untimely death in 2013. Recordings from those concerts have just been released as “The Art of Piano Duo: Live,” a three-CD set full of lively, tussling renditions of jazz standards. Barron and Miller are two nonpareil accompanists, but they’re also freewheeling improvisers who relish a good disruption: They can give each other breathing room, and then cut in swiftly to fill it all up again. The collection ends with a fleet take on “Joy Spring,” by Clifford Brown. RUSSONELLO
