A furious and fragmented reconception of Shakespeare's "The Tempest" is being staged by Italy's Motus Theater Company, which may be the most truly revolutionary troupe in town. This work is a full-throated, theatrically inventive cry to the young and disaffected to get off their collective duff, shake off their shackles and do something. Ariel and Caliban, unite! You have nothing to lose but your chains (1:20).
