Auditions will be held for the season opener “Dreamgirls.” The musical is the Michael Bennett Broadway hit musical about a Motown-style female vocal trio who rise to fame and then battle against unsavory record executives and the appropriation of their hit song by white singers. There are several non-singing supporting roles still to be filled open to all actors in addition to the principal roles specifically for African American men and women. Dancers are also needed. Dance auditions will be held at 6 p.m., Sunday, Aug. 26.
