There are still two dates left in this year’s summer concert series at Red Rock Park. All concerts are free and open to all. The remaining shows will take place Thursday, featuring MaryBeth Maes, and on Aug. 31, when the Lexington Street Band performs. Both concerts are from 6 to 8 p.m. The Lexington Street Band concert was originally scheduled for July 24, but was rained out. The series is organized by the Friends of Lynn & Nahant Beach. Meanwhile, LynnArts is holding its annual members’ exhibition this month at the Time Warner Gallery in the LynnArts building 25 Exchange St. The exhibition features the works of about 25 visual artists. Also this month, Inside Out, an exhibition of the works of the visual artists, Pamela Perkins and TANYA, is being presented in the Community Gallery of the LynnArts building. Both exhibits run through Sept. 5. The public is invited to an opening reception for the two exhibits on Saturday from 2 to 4 p.m.
