“We Move Like the Sea IV” is one of Xochi Solis’ works at Mass Gallery. Contributed by Mass Gallery.

This group show features the works of three contemporary artists, David X. Levine, Kaz Oshiro and Xochi Solis. Long associated with improvisation, the musical term “extended technique” refers to a variety of unorthodox approaches to playing a musical instrument.

The diverse methodologies of the three artists challenge and expand the boundaries of their own mediums. They approach their work with a musician’s spirit of free play and improvisation.

Details: 5 to 8 p.m. Friday, noon to 5 p.m. Saturday and Sunday through June 4. Mass Gallery, 507 Calles St., Suite 108. 512-535-4946, massgallery.org.
