Twisted Strings, acoustic duo of Michele Roy on fiddle and Will West on guitar and Irish bazouki, will offer old and new tunes with Celtic roots for contra dancing Thursday, May 8, from 7:30 to 10 p.m. at the historic Thomaston Academy on Main Street in Thomaston. Maggie Robinson will call. The steps are easy, but there will be a lesson at 7 p.m. for beginners.

Contra dancing is a popular tradition in New England and provides the opportunity to burn a few calories in time to the lively music and to meet new folks in an informal setting. It is also permissible to simply observe and enjoy the music.

This event is part of Georges River Land Trust’s Revelry for River series. Tickets are $15 in advance or at the door and limited to 80 participants. Refreshments will be served. No partner necessary. There will be door prizes, including best dancer and beginner dancer. All proceeds will be donated to the land trust.

The George River Land Trust’s third season of Revelry for the River includes a full year of diverse activities. Upcoming events include ragtime music in Rockport, the Gardens in the Watershed Tour, folk music in Owls Head and exclusive visits to lesser known watershed and coastal places — all showcasing the beauty of the Georges River watershed and continuing the celebration of the land trust’s conservation success in Midcoast Maine in its 27th year.
