No band in Lawrence takes its shit quite as seriously as Mammoth Life. The cultish eight-piece collective releases its songs on transparent blue vinyl and divides its members into teams that create “aural,” “visual” and “lingual” art. Want more? The group dresses in its own line of frilly apparel and sends out verbose press releases extolling the virtues of “emotional immortality” and “individuality, creativity and freedom acquired from knowledge.” It’s heady stuff, but Mammoth Life backs it up with twee chamber-pop that’s ambitious in scope and profound in purpose. The group’s forthcoming opus, An American Movement, invokes the spaghetti-western paradigm to tell the story of a character named Boy Blue, Who can do anything he wants to do. For absolute sincerity and dogmatic pop, live in the manner of the Mammoth.
