There’s nothing about Shitty Mozart that isn’t deliberately low rent and shabby, from his dodgy Amadeus wig that looks as though it was foraged from a skip to the crude cartoons this filthy composer presents on a screen behind him. Performer Aaron Nemo revels in DIY humour, wrestling ideas from his makeshift musical instruments to provoke belly-laugh gags about bodily fluids, darkly surreal flights of fancy and bristling gross-out satire. 

The premise here is both endearingly dumb and glaringly ropey, as though Nemo wrote down the words ‘Shitty Mozart’ on a sheet of paper to amuse himself and worked backwards from there. Scientists have attempted to clone Austria’s genius composer but, having used a pubic hair of Wolfgang’s for the job, they ended up with Shitty Mozart, a man whose own musical efforts resemble a disturbed child’s drug-induced nightmares. Even more wild are the music videos, sidekicks and skits that Nemo interacts with during this multimedia show, which riff on the influences of mid-2000s internet subversions like Newgrounds and David Firth, a wild west of comedy happy to shock and surprise. 

As he hides behind a laptop introducing a series of comic characters, unleashing bees on his audience and coaxing his crowd to chant about penetrating corpses, the gloriously puerile streak to Nemo’s humour is set alight by his wholehearted commitment to originality. As far as late-night fodder goes at the Fringe, this down-at-heel creation is an audacious wander through a weird, intelligent and mischievous comic mind.
