Windy, wintry days are best spent indoors. So stay inside and double up on tonight’s twin concerts by the University of Alberta’s Concert Band and Symphonic Wind Ensemble, where the wind is warm, melodic and instrumental. Dr. Angela Schoeder directs both programs, as U of A performance students take on the challenging works of contemporary composers including Frank Ticheli, David Maslanka and Michael Daugherty. Tonight’s concerts precede tomorrow’s free backstage tour and ESO info session, which takes place at noon at the Winspear Centre. Students and seniors receive discounts to tonight’s event.
