Tooth is a Basque experimental music project that has been active since 2007. The project is the brainchild of musician and sound artist Iñigo Muguruza, who is also known for his work with the bands Negu Gorriak and Kortatu. Tooth's music is characterized by its use of found sounds, field recordings, and electronic manipulation. The project has released a number of albums and EPs, including "Errautsetatik" (2017), "_Amaierarik Ez..." (2019), and "bi" (2021).
