Fionn’s Alanna and Brianne Finn-Morris might be young, but don’t let that fool you. The 19-year-old twins from White Rock, British Columbia, have been singing together for most of their lives, forging folk-pop sound centred around the sort of telepathically tight vocal harmonies that only siblings could deliver. Lyrics that deliver both sharp social commentary and poignantly personal reflections are backed by arrangements that range from lushly orchestrated balladry to boot-stomping roots-rock. At the heart of it all, the intertwined voices of Alanna and Brianne sparkle, singing songs that suggest an old, wise soul dwells behind Fionn’s fresh faces.
