無 (MU) is a London based avant-garde band formed by Sergio Calderón & Céli Lee, visual artists and musicians. The band incorporates diverse styles, instruments and undiscovered approaches.

Since 2015, they have been exploring live improvisation of guitar sound, volume, weight and texture. Their live shows are a blend of noise, drone, metal and power-ambient with minimalist compositions and improvisations. But they don’t want to be attached to any genre or expectation, 無 compositions are free. Their sound pieces have been originally included in exhibitions, films and installations.

無’s work includes the film soundtracks of STRANGELOVE, EVENT No. 3, EVENT No. 4, LUCILE and Impossible Yes. On 15th April 2016, they premiered CHIMERAS at fRUITYSPACE, Beijing, a performance of live music and film by Sergio Calderón & Céli Lee. In fall 2016 they begin their first tour in Japan, presenting L'Impossible. In 2017 無 are touring EVENT No.2 with shows in EU and Japan.
