Since their 1997 debut, Mogwai Young Team, this Scottish band have consistently trailblazed new and far-reaching sonic zones via glacial post-rock that relies on moments of solitude and apocalyptic tidal waves. Their longer songs (“New Paths to Helicon,” “Like Herod”) paint colossal sound canvases that build from quiet melodic motifs to huge cataclysms of distorted guitars and steadfast walls of drums. Their later music finds tension in sparse moments as they experiment with more fleshed-out instrumentation (“I'm Jim Morrison, I'm Dead”) and neo-Krautrock vibes (“Mexican Grand Prix”).
