Matthew Epstein’s departure from his job as artistic director of Chicago Lyric Opera was a surprise. Does it signal a change of direction for the company? “Clashing personalities may be a factor in Epstein’s departure. Artistic differences certainly play their part. Without a doubt, he could once again set himself up as a powerhouse consultant to opera companies and artists. We can hope that his longtime friends and new clients won’t boycott Lyric out of some sense of personal loyalty. With or without Epstein, it remains one of the world’s great opera houses. Whether it remains one of its most exciting only time will tell.”
