Transgression is a breathtaking showcase of urban sports skills, taking in BMXing, skateboarding, inline skating, freerunning, even extreme unicycling. Performed on one of the Fringe's most unique venues - a full skate park and ramps surrounded by a beach, constructed in the heart of the city.

It's an impressive display of young talent (some very young) from the EHX skate park, with at least ten heart-in-your-mouth moments. Terrifying back flips, exhilarating 360s and 540s and death-defying jumps, hand plants, leaps and technical skills.

However there is no real structure to the show, with each discipline taking turns to prove their skills, with some beatboxing, crunching guitars and breakdancing thrown in for good measure. And while constantly thrilling, it becomes repetitive (especially when a trick isn't landed and is repeated until successful). But it's a welcome and singular jolt of adrenaline to the Fringe.
