It’s a rare treat to discover a debut like Alvvays’. Each of the nine songs on the Toronto band’s first LP is a sharply drawn indie-pop wonder, steeped in romance, wit and melody. The unsentimental proposal “Archie, Marry Me” is the kind of song some acts spend careers trying to write: “Forget the invitations, floral arrangements and breadmakers,” singer Molly Rankin suggests over swoon worthy guitar jangle and a driving backbeat. The shy come-ons of “Party Police” are just as impossible to resist. Whether you’re looking to fall in love this summer or pine away unrequited, you won’t find a better soundtrack than this.
