ARCADIA – The singer-songwriter duo known as Middle Sister will perform at the Arcadia Round Barn on Sunday, July 2. The 1 p.m. concert is part of the Elm Tree Concert Series.

Robin Brooks and Susan Pierce went to music school together, and reconnected years later. They share their stories through a distinctive acoustic blend, spotlighting vocal harmonies, diverse instruments and imaginative lyricism.

Venues in which they have performed include the Oklahoma City Philharmonic, the OKC Arts Council’s Art Moves programs, Belle Isle Brewery, Full Circle Bookstore and the Oklahoma City and Paseo arts festivals.

Elm Tree Concerts are beneath the shade of the elm tree on the north side of the Round Barn. Admission is free but donations are accepted for the maintenance of the nonprofit museum. Guests can bring lawn chairs or sit at the picnic tables.

The Round Barn Rendezvous is scheduled for Sunday, July 9, from noon to 4 p.m. Musicians of all skill levels are invited to bring their instruments and join the monthly jam session.

The Round Barn is six miles east of Interstate 35 on Route 66 and is open every day from 10 a.m. to 5 p.m.

For more information about live music at the barn, call Joe Baxter at 405-833-1350.
