Uboa is the musical project of the Australian drone, ambient and noise rock artist Xandra Metcalfe. She began in 2010 during a period when Metcalfe experimented with doom metal textures and home studio equipment, and gradually moved towards noise, experimental and abstract compositions.
Metcalfe has collaborated as Uboa with several other noise artists including Slumber Kitty, Muddy Lawrence, Solus Varak, teeth dreams and has produced a split EP with Bolt Gun.
