Bearing 'Witness'

Thirty years ago, Philip Brunelle's choir VocalEssence initiated a project called "Witness," which aimed to "celebrate the artistic contributions of African-Americans to the fine arts and to our common cultural heritage." The anniversary is marked this week in "Deep Roots," a landmark celebration of a program which over the years has featured artists such as Bobby McFerrin, James Earl Jones and Spelman College Glee Club. T. Mychael Rambo and Jovonta Patton are among this year's guests, and a 30th Anniversary Community Choir joins the VocalEssence singers.

"Experimental opera" is an increasingly popular genre that aims to wrench opera from its traditional formality and drag it into the 21st century. The composers collective 113 is bringing the format to the Twin Cities in "The Golden Ass," an opera by its artistic director, Tiffany Skidmore. Based on the classical myth of Cupid and Psyche, Skidmore's piece focuses specifically on the psychological relationship between Psyche and her vindictive mother-in-law, Venus. Carrie Henneman Shaw and Elizabeth Pearse sing these parts, with 113's co-founder Joey Crane directing. (7:30 p.m. Fri. & Sat., 2 p.m. Sun. Nautilus Music-Theater, St. Paul. $5-$15,
