OO.OO are a musical duo – and brother and sister – comprising OO and OO. One is based in Denmark; the other in Los Angeles. Pitchfork described their debut album as “a waste of everyone’s time and energy”. Little has changed since then. By their own account, they made a name for themselves internationally with music that is difficult to explain, and are now setting foot on Dutch soil, where OO.OO promise to cause chaos, at the very least.
