JACK Quartet

The JACK Quartet — a New York string quartet with a new-music mission — is capping a weeklong residency at the University of Washington School of Music with a show devoted entirely to UW composers.

The program includes the world premiere of "Aperture II," for amplified string quartet and live electronics, by School of Music director Richard Karpen. Also on the roster: Juan Pampin's "Interstices" ("kind of a world premiere," the composer says, "since the electronic layer has been composed this year and the piece has never been played with it") and pieces by Joel-François Durand and Huck Hodge.

7:30 p.m. Friday, Floyd and Delores Jones Playhouse, 4045 University Way N.E., Seattle; $12-$20 (206-543-4880 or www.music.washington.edu).
