Two new ephemeral art installations curated by McCarthy-Swann Projects – The Weight of Light and The Size of Air – will take over the public spaces from now until late October.

Running through to Saturday 23 September, the heritage-listed Spring Hill Reservoir will take on a futuristic form with a new commission by Brisbane artist Meagan Streader, who will use electroluminescent wire to frame the architectural features of the CBD’s most intriguing underground space, which was once the source of water for the City of Brisbane. Visitors will marvel as they descend the stairs into the reservoir and walk under and through lines of light carefully mapped by wire stretched across space, wrapped around architectural features and crafting new shapes and spaces in the air.

Then, for three days only from Wednesday 25 to Friday 27 October, The Size of Air will transport Brisbane’s Queen Street Mall as experiential artist Kinly Grey’s pop-up cube – the twelfth instalment of Grey’s blue series, an experiment with scale and space to produce immersive, sensory, site-specific environments and ephemeral works inside and outside of galleries. With transparent walls filled with a thick white fog, and images of a clear blue sky projected across its surface, visitors can enter the calm and reflective cube and into a piece of the river city’s sky.

Kieran Swann of McCarthy-Swann Projects says the wondrous urban activations are set to transform the two iconic Brisbane locations through inventive, contemporary visions and distinct local character.

“The two springtime art installations invite all to experience a new reflection on the Brisbane cityscape – ephemeral and experiential. It’s a chance to experience art in our city in a new way. We’re proud to present these two really visual and immersive pieces of contemporary work by incredible local artists and can’t wait for Brisbanites to step into these spaces to take it all in.”

The Weight of Light and The Size of Air are supported by Brisbane City Council.
