The date has been set for the grand reopening of the refurbished and historic Academy of Music Theatre (600 Main St.) at the Academy Center of the Arts, and the opening event of the opening week has been booked. Mavis Staples, a legendary gospel and soul singer who’s legacy dates back to the 1950s and who continues to be a force both on stage and off, will headline “In Unison,” a concert marking the integration of the theater, which opened in 1905 and closed prior to desegregation in 1958. Staples, who got her start performing with her family in the Staples Singers and has reemerged as a singular solo artist over the past decade, will be joined by the up-and-coming Nashville-based singer and songwriter Devon Gilfillian. Tickets for the 7:30 p.m. show run from $25 to $182. For more information, click here or call (434) 846-8499.
