Sketch shows can often seem lacking in dramatic momentum. Not so with We Are Klang, who pile-drive through the format with bulldozer energy. The trio's new show, Klangbang, is just the ticket if you like comedy that pours with sweat and looks as silly as possible.
As with all good comedy troupes, much of Klang's art is in the relationships within the threesome. Strapping Greg Davies is the authority figure, insisting on professionalism as all around him collapses. Marek Larwood is his natural foil: a bumbling clown, naked from the boxer shorts down. It's harder to see where Steve Hall fits in, although all three enthusiastically take part in the acts of mutual sabotage that form much of this ramshackle show.
Highlights in this regard include the World Insults Championship, in which Larwood brands Hall a "poor man's David Baddiel". Hall ripostes with "homeless Matt Lucas", and Davies is dubbed "a very, very fat Rik Mayall". The audience is asked to join in, then blamed for going too far. But when the mutual humiliation becomes arbitrary, it gets tedious, as in a later sketch in which Davies does squat-thrusts while Larwood stuffs his mouth full of grapes.
Klang sometimes blunder across the fine line between liberating idiocy and puerility. And, like many male sketch troupes, they are crass about women and too interested in one another's nipples and arses. That might get boring if the trio weren't so adept at fomenting hilarity. Witness Davies playing mentalist Darren Chilblain: "Your mind is an egg. How would you like it: fried, scrambled - or blown!?" They end their set with a smutty but jolly audience sing-along that all but lifts the roof off their shoe box of a venue. With the skills to stoke that kind of atmosphere, We Are Klang should steamroller all resistance.
