Unsound Adelaide returns to its original and arguably most beloved venue, The Queen’s Theatre, for a night that ranges from the delicate to the overpowering. Nicolas Jaar is one of the best known electronic musicians of his generation. While Jaar’s club music has always involved sonic exploration, in recent years his career has increasingly focused on experimentation - and he comes to Unsound Adelaide to perform an ambient A/V show. For their first Australian concert in five years, Matmos return with an exclusive presentation of new material from their forthcoming album for Thrill Jockey Plastic Anniversary, which will focus upon the sound of everyday and not-so-everyday plastic objects. Forcing us to see and hear the transparent and disposable detritus that keeps daily life going while keeping their sense of humor intact, you can expect audio and video that wrenches twitchy patterns and freakish noises from seemingly banal materials. They might even play some classics from their back catalogue if you're nice. Eartheater opens with a dreamlike performance, combining digitally manipulated sounds, acoustic instrumentation, and her impressive three-octave voice, exploring the ambiguity of words, moral surreality and the evolution of sexuality in a digital age. Closing is Giant Swan, the duo Unsound dubbed “Bristol’s best kept secret” in their Kraków write up last year. Since then, they’ve pulverized audiences around the globe, from Europe’s key clubs through to Uganda and Kazakhstan. Combining punk energy and hardcore techno beats with a dash of psychedelic improv, they’re a force to be reckoned with. Cutting into the middle of the night with a brief burst of sonic terrorism is Sydney’s one-and-only Lucas Abela, who will play one of his infamous - and increasingly rare - shows in which the main instrument is a piece of amplified glass.
