Efficient Space continue to expose Australia's esoteric musical history with Oz Waves - a collection of '80s DIY recordings, compiled by odd wave anthropologist Steele Bonus. Definitive proof that inhabitants of the Down Underground were links in a global network of creative kooks, Oz Waves connects those who utilized mobile recording rigs and small press releases to create and disseminate misfit synth-punk, tape loop experiments, and inner city pop. Through overseas mail order exchanges, anonymous groups like Zerox Dreamflesh could find place on Belgian compilations, while Chris and Cosey lullabied their son to sleep with Irena Xero and her interdisciplinary art collective Zip. Bonus selects ten survivors from the fertile period (1982-1989), most of which were only issued on cassette in tiny editions of five to one-hundred copies. M Squared affiliates Prod join the extraterrestrial Software Seduction, He Dark Age's minimal wave neglect and the irreverent cut ups of The Horse He's Sick and MK Ultra & the Assassins of Light. The remaining tracks have been sourced from musicians' private archives and are being officially released on Oz Waves for the first time - Andy Rantzen's industrial dub Itch-E & Scratch-E precursor, the buoyant vocal-drone of Ironing Music, and Moral Fibro, Sydney's short lived answer to Weekend and Marine Girls. With detailed track-by-track notes, lines are drawn to Severed Heads, Scattered Order, and other antipodean post-punk royalty. As a DJ, Steele Bonus has gained notoriety via the exquisite selections that form his ongoing mix series Odd Waves. Sydney-born, Amsterdam-based, his graphic design has not only been responsible for sleeves on Efficient Space, but also trusted Amsterdam connoisseurs Music From Memory and Young Marco's Safe Trip.
