The Wailin’ Jennys

Firecracker

8:15 p.m. Saturday and 3:30 p.m. Sunday at California Worldfest at the Grass Valley Fairgrounds. Visit www.worldfest.net for info.

A punster might call this Canadian trio the Mason Chicks; comparisons to their Texas counterparts are inevitable. But the Wailin’ Jennys—Annabelle Chvostek, Nicky Mehta and Ruth Moody—put a folk spin on north-of-the border harmonizing that crosses genres. Sharing songwriting credits and rotating lead vocals, they add an Appalachian twist to “Swallow,” throw a bit of gospel into “Glory Bound” and “Starlight” without moving into preacher mode, take a quick lick at the blues with “The Devil’s Paintbrush Road” and add a touch of enviro-political commentary in “Apocalypse Lullaby.” Their a cappella version of the traditional “Long Time Traveller” is pitch-perfect—proof that the Jennys have it all. If you can’t catch them live at California Worldfest in Grass Valley, don’t miss Firecracker.
