If you’d like to learn more about traditional Canadian music and performance styles from Canada’s Ottawa Valley, just watch April Verch as she sings, stepdances and plays fiddle — especially when she accomplishes two or all three of those tasks at once. Prism Coffeehouse presents an evening that also will include Appalachian music and other North American favorites as Verch’s band adds guitar, mandolin, bass and clawhammer banjo to the mix. $18 dos; $16 adv. prismcoffeehouse.org.
