In a rough-hewn attic over an Oxford Street bar, LO-FI Collective is one of Sydney’s newest pop-up art spaces. The display area is separated by chain-link fence from the benches and mess of the artists’ workspaces, the clean mesh standing out sharply from the faded paint on the walls and unpolished, ill-fitting floorboards.

The worn-down, industrial aesthetic fits neatly with Thomas Jackson’s skeletal sketches, which features a series of drawings on math-book style grid paper. Jackson creates an unfinished air in his work, peppered with notes scribbled in the margins and the seeds of ideas linked by arrows to the images. Across the beautifully shaded sketches of birds, whales and turtles, Jackson’s colour seems to have seeped through from below in patches, or to have been revealed by scratching away an upper layer.

The other artist on display, the enigmatically named TWOONE, is much heavier in detail. Like Jackson, there’s a strong theme of animal imagery, focusing in this case on the picked-clean skulls of cattle, sheep and goats. These skulls replace human faces in bizarre and creepy images that integrate an air of divinity in the form of halos and priestly vestments.
