Groundbreaking Mexican RIO (Rock In Opposition) type, cross-culture, rock, folk and jazz hybrid band with different line-ups, invited artists and activity periods until now. They started as a progressive rock trio in late 1973, inspired by EL&P, founded by Walter Schmidt (3) (bass), Carlos Robledo (keyboards) and Moisés Romero (drums).

Gradually they were becoming an experimental chamber orchestra by adding various percussion, strings and brass instruments like violin, saxophone, mandolin, marimba, flute, harp, clarinet, guitar, among others, also fusing synthesizers and electronics —allegedly inspired by Henry Cow.

By the release of their iconic first record, Decibel - El Poeta Del Ruido, the group was already disbanded and its members went on to form genre-defining bands in Mexico like Size, Casino Shanghai, Nazca, Subsuelo, Syntoma, Vía Láctea, Chac Mool, Los Agentes Secretos, Queso Sagrado, Banda Elastica, OD, Cou Cou Bazar and Fist Of Facts, along with many others that by the time couldn't even record any release properly.

Since then, Decibel has intermittently gotten together to make other recordings and in the nineties they released 'Contranatura' (1992), 'Mensaje Desde Fomalhaut' (1996) and 'Fortuna Virilis' (1999).

In 2010, Walter and Carlos invited Alex Eisenring to collaborate with Decibel yet as another revival. Alex had been around twenty years inactive, just working in 3D animation, video editing and graphic design. By 2012 they were performing live for Georges Méliès short films projections as well as other silent short films from surreal cinema movement.
