Eric Orr's work of recent years trades heavily on past glories. An artist firmly pigeonholed as trafficking in perceptual matters, he apparently needn't bother anymore to offer tangible proof.
A group of paintings called "Time Windows" contain glowing electric blue or bright red rectangles--some nicked with white slashes of paint, some softened with passages like longhaired rugs. "Radio Plays" replay the Orr-as-shaman fascination with blood and crushed bones and itty-bitty ground-down electronic parts. Delicate gold perspective lines glide back in space.
"Naked Singularity 3" is a hypnotic grooved slate slide that pulls a sheet of water down in stubborn little puddles that keep re-forming in ways too devious for the eye to see. But it all seems like remedial study material for those who haven't passed Sensory Awareness 101. The class is waiting for Professor Orr to unveil some new tricks, but not the parlor variety.
