The Francestown Old Meeting House, 1 New Boston Road, will host its free “Sundays at 4” concert series outdoors on the lawn each Sunday from July 6 through Aug. 24.

All performances begin at 4 p.m. and end around 5 p.m. Attendees are encouraged to bring a picnic and a chair. Dancing is welcome, and in case of inclement weather, concerts will move indoors.

The season opens July 6 with Acoustic Nomads, a Boston-based band blending musical traditions from across the Americas. On July 13, Irish folk band Ishna, led by Ciaran Nagle and Tara Novak, presents traditional tunes with new rhythms and harmonies. July 20 features Americana, folk and blues from the Twangtown Paramours. On July 27, Marsh Lights performs original acoustic folk-grass music.

August concerts begin with vintage jazz trio The Hot Skillet Club on Aug. 3, followed by early jazz and ragtime from Mill City Rags on Aug. 10. Guitarist JP Stohrer performs blues- and jazz-influenced instrumentals Aug. 17. The series concludes Aug. 24 with Francestown native Jacob MacKay, cellist with the Apple Hill String Quartet and co-artistic director at Apple Hill Center for Chamber Music.
