BATH — The fiery Celtic style of Còig, who have sold out four consecutive holiday concerts, will open the 2017-18 Chocolate Church Arts Center performance season at 7:30 p.m. Sept. 8.

Fiddler Chrissy Crowley joins Rachel Davis on fiddle, viola and vocals. Pianist Jason Roach possesses a style all his own, and an unparalleled intensity on the keys. And Darren McMullen commands guitar, mandolin, mandola, banjo, bouzouki, whistles, flute and vocals.

With driving tunes, haunting songs, and infectious energy, Còig is an unparalleled musical force. Irish music enthusiasts will enjoy the Gaelic spinning songs of these Cape Breton musicians. Much of the music of this region is Celtic in nature, but originates in the local area and celebrates the sea, seafaring, fishing and other primary industries.

Tickets are $20 advance and $23 at the door.

The theater season begins the following week with the debut of the Rodgers & Hammerstein’s musical “Oklahoma.” The holiday-themed theater production has been expanded for two weekends in December. The winter production is presented in the annex in late February. “MacBeth” concludes the season in June 2018.

The remainder of the season highlights iconic musicians, such as the Home Again: Carole King tribute on Oct. 21; Dave Mallet, March 24; and Jonathan Edwards returns to the main stage April 20. During the holiday season, the Chocolate Church continues to offer a variety of musical treats from Motown Christmas with Pat Colwell and the Soul Sensations on Nov. 25; Celtic Christmas with Turning of the Year on Dec. 9, and the Sweetback Sisters return with their County Christmas sing-a-long Dec. 8.

Family entertainment is planned throughout the 2017-18 performance season with the all-ages show with Master illusionist Vitaly on Oct. 8; Christmas is Magic, Dec. 2; and a one-woman show, “The Belle of Amherst,” about poet Emily Dickenson, April 29.
