Crystal Magnets

Melding minds under the apt name Crystal Magnets, Andy Milne and Benoît Delbecq conjure a fascinating array of textures from two prepared pianos, bridging the worlds of post–John Cage composition and impressionistic jazz. This week, the duo stages a residency at ShapeShifter Lab, incorporating different guests each night: pianists Ethan Iverson and Fred Hersch on Nov 28 and 29, respectively, and reedists Michaël Attias and Greg Osby, along with brass specialists Vincent Chancey and trombonist Jacob Garchik, on Nov 30.
