R. Mutt was an experimental post-punk / electronic group formed in 1986 by Bruno Verner on vocals, guitar, keyboards and sampling (also on Tetine, Divergência Socialista, Ida & os Voltas), Karla Xavier, on vocals, keyboards and percussion (also on AKT), Bernardo Rennó on drums, keyboards, electronics and percussion (also on Ida & Os Voltas), Marcos Basho on bass-guitar and Frederico Pessoa, bass-player on the first line-up. Making use of drum machines, synths and cheap samplers, R. Mutt's dystopian echoing soundscapes combined glacial electronic instrumentation with female and male half-spoken/ half-sung vocals; folk introspection, dark basslines & metal percussion, with poetic dada-surrealistic lyricism.

Part of the art-punk scene from Belo Horizonte of bands such as Divergência Socialista, Ida & Os Voltas, Sexo Explícito, O Último Número, Hosana Nas Alturas, Xiitas, Alma Ciborg, Os Contras, Sylvia Klein, Crime-Ópera amongst others, the group disbanded in 1989 with Bruno Verner later forming Tetine with Eliete Mejorado in the early 1990s in São Paulo, and vocalist & keyboard player Karla Xavier forming the all-female post punk outfit AKT with Sandra Coutinho (of Mercenárias), Biba Meira (of Defalla) & Dequinha (Bruhaha Babélico), and later on, The Gilbertos with her partner Thomas Pappon (also on Fellini).
