Jace Lasek is a well-known producer in his home country of Canada, having worked with bands such as Arcade Fire, Land of Talk, and Wolf Parade at his Breakglass Studios in Montreal. So perhaps it’s no surprise that Lasek’s own project (which he started with his wife, bassist/vocalist Olga Goreas), The Besnard Lakes, creates ambitious, meticulously crafted rock albums. The attention to detail extends to his lyrics: Back when the band formed ten years ago, Lasek created a storyline about two spies “who are chasing each other and have a love-hate relationship,” according to an interview he did two years ago with Philadelphia Weekly — a theme that continues today. The band’s fourth album, Until in Excess, Imperceptible UFO, is, at times, hazy, dreamy, poppy, noisy, and anthemic — made all the more intoxicating by the vocal interplay between Lasek, who sings falsetto, and Goreas, whose petal-soft voice makes songs like “People of the Sticks” particularly gorgeous. The Besnard Lakes will perform at Brick & Mortar Music Hall (1710 Mission St., San Francisco) this week, with Montreal’s Elephant Stone.
