Conference host Eric Berlin joined the program to perform [four movements from] Stephenson’s Vignettes for Trumpet and Percussion with Eduardo Leandro on percussion. Each of the . . . movements paired the trumpet with a single percussion instrument. The finale, “Dinner with Andre,” was a particular highlight featuring Berlin’s piccolo pyrotechnics and Leandro’s astonishing tambourine playing. This charming, witty piece was a big hit with the audience, eliciting infectious applause after many of the individual movements.
