In the Lehigh Valley, classical music doesn't disappear in the summer. Instead, June signals the joyful return of Valley Vivaldi, a series of delightful Baroque chamber ensemble concerts by principal instrumentalists of Pennsylvania Sinfonia Orchestra. On June 9, the repertoire includes works by Vivaldi, Handel, Pergolesi, Telemann, J. S. Bach, with concertos featuring flutust Robin Kani and oboist Cheryl Bishkoff. Meet the musicians at the post-concert reception.
