"I really dislike music," says a cop ironically named Amadeus, and this ingenious Swedish comedy soon makes it clear why. His younger brother is a pompous, famous symphony conductor; his father is an overbearing musician, too; and poor Amadeus is tone-deaf. For him, then, the worst possible case to investigate would be a rogue gang of percussionists who make the whole city a venue for performances that the authorities call terrorism. Sneaking into a hospital, they commandeer an OR, then use the oxygen machine, beeping heart monitor, surgical steel, and a patient's bulbous gut to play a delightful conga. Taking their rhythmic anarchism even further, they steal road-construction machinery and perform a symphony for jackhammer and wrecking ball.
