Stravinsky’s The Firebird, a ground-breaking ballet, became an instant sensation when it premiered. Based on a Russian folk legend, it features “gorgeous melodies, fierce rhythmic intensity, and one of music’s most breathtaking finales.” Tonight at 7:30 at Severance Hall, the Cleveland Orchestra performs the composer’s 1945 suite from The Firebird. A pre-concert talk takes place an hour before the concert in Reinberger Chamber Hall at Severance Hall. Tickets start at $29 and performances repeat at 11 a.m. and 7 p.m. tomorrow and at 8 p.m. on Saturday. (Niesel)
