Sunn O)))) formed in March 1998 in Los Angeles. A synthesis of diverse: drone, ur, noise, metal, minimalism/maximalism; supported by a cast of collaborators, O))) has two core members: Stephen O'Malley and Greg Anderson. For twenty years, Sunn O))) have been challenging the way we think about music. From 1999’s The Grimmrobe Demos to 2021’s Metta, Benevolence, 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. While Sunn O))) history of artistic collaborations is legendary, in celebration of their 25 years founders/guitarists Stephen O’Malley & Greg Anderson returned to the live aspect in its core, original raw form and performed several tours across Europe and North America as a duo. Their concerts are storied with remarkable performances at some of their favourite venues, as well as performing in new cultural spaces such as David Geffen Hall at Lincoln Center in New York, Italy’s impressive cultural complex Labrinto Della Masone, Germany’s Ruhrtriennale Festival of Arts, at The Barbican, London and Manchester International Festival being a few fine examples. All hail.
