Nolan Murray and Pat Chessell perform as Rough Cut for an Olympic Theatre Arts benefit concert set for 7:30 p.m. Friday, July 20.

Murray and Chessell have set an evening of traditional Irish music, original Celtic and a touch of “Americano” on Friday in the OTA Center Gathering Hall, 414 N. Sequim Ave.

A member of both Tiller’s Folly (who recently headlined at the Juan de Fuca Festival of the Arts) and The Whiskey Minstrels, Murray has a long history as a for-hire multi-instrumentalist — fiddle, mandolin, mandocaster — who at an early age parlayed a list of championships into a touring/recording career that has spanned decades and has cut more than 280 albums.

Throughout that time, he’s left his musical imprint with a long list of iconic performers including Loretta Lynn, Brenda Lee, John Fogerty, The Irish Rovers, Randy Travis, John Cowan, Ricky Van Shelton, David Frizzell, Patricia Conroy, Gary Fjellgaard, Jess Lee, Funk Brother’s Bob Babbitt and Wrecking Crew’s Larry Knechtel.

Chessell, a singer and guitarist called “a force to be reckoned with” by Catholine Butler at The Celtic Connection, has played all across Canada, throughout upstate New York and in his ancestral homeland of Ireland. He was a feature act in the Irish Pavilion at the 2010 Winter Olympics and has opened for such acts as Jim Byrnes, Delhi 2 Dublin, Derek Warfield and the Young Wolfe Tones, The Town Pants and more.

General admission tickets are $20 and all proceeds benefit Olympic Theatre Arts community theatre.

Tickets may be purchased in advance online at OlympicTheatreArts.org or at OTA’s box office open M-F, 1-5 p.m. (call 360-683-7326), or at the door if available.
