On September 5, James Ehnes will join the Chicago-based Music of the Baroque and Dame Jane Glover as soloist in Mozart’s Violin Concerto No. 3. He has appeared four times previously at the Ravinia Festival, but this visit will be his first since 2013. “I love playing in the Pavilion at Ravinia, but I’ve never played in the Martin Theatre, so this is going to be something new, different, and exciting,” he said. The 47-year-old violinist appeared as a soloist with Glover at the Aspen Music Festival in 2021 in the Beethoven Violin Concerto. “I just found her music-making to be so natural and so enjoyable to play with, so I’m really looking forward to being with her again.”
