As the name suggests, this program showcases the work of mentors and their students. But otherwise there are no common themes or goals. In fact, one of the mentors–Cindy Brandle, coartistic director of the Chicago Moving Company–created Duplicate out of the impulse to avoid any kind of concept. Dressed in simple black, she, Elizabeth Lentz, and Mindy Meyers produce a kind of line drawing onstage, a drawing complicated by its elaboration over time. Echoing one another’s movements to Moby’s music, they make us meditate on the different look and feel of arms raised overhead in various ways. Brandle’s student, Tiffany Bowden-Van Cleaf, has choreographed a piece in which each of six dancers recites a story about her hometown. Anna Simone Levin, artistic director of Same Planet Different World, offers a solo about a common dream theme–appearing nude or seminude in public–while 1938-1954, created by her student, Dmitri Peskov (also the instigator of this showcase), was inspired by his Russian grandmother’s recollection of internment in a Stalinist concentration camp. Independent choreographer Paula Frasz, a former Mordine & Company dancer, set her solo Lowering Clouds on her student, Tracee Westmoreland, also a former Mordine dancer; and Westmoreland has choreographed a piece about the way the senses inflect memory. Performance Loft, Second Unitarian Church of Chicago, 656 W. Barry, 773-529-8522. Opens Saturday, August 18, 7 PM. Through August 26: Saturday-Sunday, 7 PM. $12-$15.
