On the opening night of “Ballet, Brass & Song” at Sidney Harman Hall June 22, the Moche Brass Band welcomed guests outside the theater before proceeding to the stage for “Rue Noir,” evoking the pulse of the French Quarter. The program included five ballets, three choreographers and three music ensembles. Choreographer Diane Coburn Bruning has assembled her troupe of dancers from major ballet companies and D.C.’s finest brass, jazz and chamber musicians. Founded in New York in 2000, the company has just completed its fourth season in D.C., fulfilling her conviction that dance should be performed with live music in smaller venues. VIP ticket holders enjoyed a post-party with the artists on the upper mezzanine.
