SML is one of our era's most beguiling bands: a collective rooted in group improv, with a blend of loopy groove, staticky texture and shifting timbre. Three of the band's five members — bassist Anna Butterss, saxophonist Josh Johnson, and synthesist Jeremiah Chiu — join Julian Booker to talk about their commitment to shared discovery.

The gayageum is a plucked Korean zither with a history that stretches to the sixth century. Its first and finest exponent in avant-garde jazz is DoYeon Kim, whose spellbinding debut, Wellspring, reveals a fiercely original voice. She joins us to talk about tradition, translation, and the power of self-expression.
