For sixteen years, Sunn O))) have been challenging the way we think about music. In that relatively brief time, core members Stephen O’Malley and Greg Anderson have forged connections between the worlds of Metal, Drone, Contemporary Composition, Jazz and Minimalism with startling results while remaining true to the eternal principles of volume, density and weight. The release of The Grimmrobe Demos (1999) sent tremors throughout the underground with its bold realisation of hitherto unimagined heaviness. Building on the innovations of Seattle pioneers Earth – and naming a track in honour of their leader Dylan Carlson – Sunn O))) forged even deeper into a realm of reverberating darkness.
