Airs Monday, May 12 at 8 p.m. Amir ElSaffar grew up around Chicago as something of a trumpet prodigy, in both jazz and classical. He was winning competitions and beginning to make a go of it in New York.

This band splits the difference, using microtonal techniques to investigate the blues. They'll have new tunes too, commissioned for Newport and supported by the Doris Duke Charitable Foundation.
