Possessor of one of the liveliest minds, not to mention highest energy levels, on the fringe circuit, Australiaâ€™s one-man wonder Jonno Katz is back in Ottawa for a second year. This time, Katz brings us the excellent adventures of brothers Roy and Sebastian. The latter is a conceptual artist with an advanced case of cluelessness; the former a self-important type with bricks for brains who decides to promote his younger brotherâ€™s laughable art project. To complicate matters, Royâ€™s marriage to Emily, a none-too-swift gal also played by Katz, teeters on disaster. Youâ€™ll have to see the quicksilver show, packed with mime and dance and hilarity, to find out more. Suffice to say that the limber-limbed Katz is superb (watch for his depiction of an esophagus at work) and his show a self-contained delight. At Arts Court Theatre until June 27.
