This evening’s theme is improvisation. Whilst solo artist, Single Unit, blasts off into his own musical universe somewhere between a rasping-rumbling cacaphony and precise abrupt breaks and Angel, supported on cello by Hildur Gudnadottir, get in sync for a single unbroken escalation of Noise-Drone kink, in the other three acts it’s dialogue that takes centre stage. John Hegre is one half of Jazzkammer, whose studio releases Jorgen Traen frequently had a finger in producing. Tonight they collide as Golden Serenades, throwing themselves with racket and verve into rambunctious conversation – or maybe it’s an argument? Electro Opera e- is a further encounter of disparate styles: Classically trained soprano, Ge-Suk Yeo sings in electronic soundscapes created by Byungjun Kwon, who draws on traditional Korean music and Jazz. Maja Ratkje subjects her voice to electronic effect machines to create tonal forms ranging from the sharp saw-toothed to the rich and organic. Her voice-and-electronica dialogue is richly underscored and extended by interaction with video images from media artist HC Gilje.
