Cape Breton master fiddler Natalie MacMaster and her high-energy band storm into George Mason University’s Center of the Arts Sunday. Her wildly entertaining shows generate packed houses, stamping feet and clapping hands as her magical fiddle recaptures traditions that originated in the Scottish Hebrides centuries ago and segues into contemporary tunes evoking bluegrass, jazz and rock.

Married to Donnell Leahy of the popular Canadian band sporting his surname, she is expecting their second child in early summer and touring with 15-month-old Mary Frances in tow, thanks to caring relatives who babysit during shows. Free to spread the power of Celtic music from the stage, she fiddles with jaw-dropping passion and sets the hall on fire whenever she executes her step-dancing prowess.
