Tonight Cain Park hosts master fiddle players Natalie MacMaster and Donnell Leahy. Hailing from Cape Breton, Canada, MacMaster has been a renowned fiddler since she was 9 years old. Leahy’s skill is on par with MacMaster’s and he’s won several JUNO awards with his family band. If you head over to the BottleHouse Brewery before tonight’s show, you’ll get a beer tasting for $10. Advance tickets are $22 to $32, $25 to $35 day-of-show and the concert starts at 7 p.m. (Gonzalez)
