Franz Welser-Möst conducts the Cleveland Orchestra as it takes on Haydn's oratorio, "The Seasons." Beethoven allegedly attended the premiere and bowed to Haydn after he heard the performance. Guest speaker Rose Breckenridge, a Cleveland Orchestra Music Study Groups administrator and lecturer, gives a free pre-concert talk an hour before the concert. The concert takes place at 7:30 tonight and at 8 on Saturday night at Severance Hall. Consult the orchestra's website for ticket prices. (Niesel)
