In Pulitzer Prize–winner Henry Threadgill’s compositions, notation and improvisation mesh in sonic expressions of American life. He calls his unique polyphonic language “creative music,” which others revere as a musical masterwork beyond category. On Friday, 20-some Minnesota musicians (curated by cellist Michelle Kinney) perform Threadgill pieces from the past 40-plus years. As potent and prolific as ever, Threadgill closes the festival on Saturday with his acclaimed quintet Zooid.

New York power-jazz trio Harriet Tubman, made up of ex-Threadgill star players Melvin Gibbs, Brandon Ross, and JT Lewis, will open Saturday’s concert.
