7:30pm King’s Theatre. Live Music. $35 Adult/ $10 Youth. At one moment a prog-rock band, the next an Irish-Scottish-Norwegian trad band, then an experimental indie-jazz band, then somehow all of these at once, Aerialists have alchemized diverse influences into a sound with striking clarity. It’s ethereal yet precise, technical yet visceral. Formed nearly a decade ago by harpist Màiri Chaimbeul, fiddler Elise Boeur, and guitarist Adam Iredale-Gray, now with three albums and a JUNO nomination under their belt, Aerialists have staked their claim on the leading edge of the neo-folk world.
