LEWISTON – Fiddler Ed Howe and guitarist John Cote will heat up the hall at a public contra dance scheduled for Friday, July 11, in Callahan Hall at the Lewiston Public Library.

The event runs from 8 to 11 p.m. Admission is $2 for students, $5 for others.

Howe and Cote, who perform under the name Perpetual eMotion, are known for mixing jazz and bluegrass influences into their repertoire of traditional Irish, French-Canadian and Scottish tunes, with Howe often taking off on impromptu improvisational excursions on his pared-down but powerful electric fiddle.

The duo will be joined for part of the evening by fiddler Rebecca Grube, a 2007 graduate of Lewiston High School who is now attending Moravian College in Bethlehem, Pa., as a music major with a concentration in Celtic fiddle.

Kat Logan will serve as the caller for Friday’s dance, leading attendees in an assortment of lively New England contra dances, which are based on a double-line formation, as well as an occasional circle or square dance. No prior dance experience is required to participate in the event, nor is it necessary to bring a partner. The custom is for everyone to mingle freely during the evening.

Callahan Hall, which is air-conditioned, is located on the third floor of the library at 200 Lisbon St. For more information, call the library at 513-3050.
