Ensconced as the house band at the ancient, ramshackle tavern The Montreal House, the original duo of Charlie Glasspool and Trevor “Tiny” Davis attracted old friends and grew from a duo, to a quintet, to an anarchic horde of over a dozen players and singers, bringing a dark, absurdist edge to their reworkings of blues, country and tin-pan-alley music, and tore into originals, standards and contemporary covers with equal ferocity and grim glee.
