THOMASTON — Maine Friends of Music, a professional chamber ensemble, returns to The Knox Museum, 30 High St., for a community concert on Thursday, July 22, at 6 p.m. The quartet is comprised of soprano Mary Sullivan, flutist Linda Brunner, bassoonist David DeBolt, and harpsichordist/organist/pianist Sean Fleming.

Maine Friends of Music specializes in quick-paced programs that create interesting listening experiences, with a variety of tone, colors and styles.
