Instant Doodle Wilson Tsang and friends Z+, 12 Oil Street, North Point, January 2 The title is self-explanatory: no meticulous pre-production, no preposterous lighting effects, no avant-garde set pieces - just an hour of dreamy soundscapes that are as incidental as they are intentional.
As the audience filed in and made themselves comfortable, Tsang's bleeps and synth waves swam across the bare venue - a former godown - sweeping at times, spiky at others.
This was no conventional show - more a surrealist 'happening'. In addition to the seemingly random beats, a child was left to his own devices throughout, running amok, covering his ears with his tiny palms as soundscapes twisted and turned.
You could be forgiven for thinking you were the only onlooker, and everyone else part of the show.
These aside, Tsang's music had a raw and stunning power. The material was a fusion of musical genres, the ingredients so deliberately contorted that they took on new meanings - jazzy stabs intercept grandiose post-rock environs, while fuzzy synthesiser notes floated amid seas of gothic gloom.
All very impressive considering Tsang's instruments were a synthesiser and two dusters - of which the handles were used to perfection as percussion.
