“Russlan and Ludmilla” is an opera by Mikhail Glinka based on a fairy tale of the same title by Alexander Pushkin. We heard the work’s exuberant overture, based on themes from the opera. The orchestra whose recording of this Glinka favorite we played recently had to cancel its entire summer concert series. A labor dispute and the orchestra’s financial crisis led to a lockout of its players this week. Which orchestra is this?
