What to see Wednesday night at the Fringe Festival:

  • "Close Music for Bodies." Everybody wear good socks. For this immersive acoustic choral work by Philly composer and sound designer Michael Kiley, the audience and singers both walk around throughout the performance — and showgoers are asked to remove their shoes. (Seating available for those unable to walk for the duration.) 7 p.m. at Christ Church Neighborhood House, 20 N. American St., 75 minutes, $29 (students $15), additional shows daily through Sept. 24

    • "The Bald Soprano." Eugene Ionesco's six-character masterpiece farce, staged by Philly's all-absurdist all-the-time Idiopathic Ridiculopathy Consortium. Our critic said you won't find a better production of this play in the region. 7:30 p.m.,  Bethany Mission Gallery, 1527 Brandywine St., 65 minutes, $15-$25, additional shows daily through Sept. 24.
