The band was created by Guillermo Garavito (drums) and Rodolfo Vergaray (guitar) in the Rimac neighborhood, Lima. Two more friends would join them later: Moisés Quino (guitar) and Daniel Rosario (Bass).

Peru had a thriving psych rock scene in the 60s and 70s and MAG (Peruvian label named after the initials of its founder, Manuel Antonio Guerrero) was responsible for most of the output of the best local bands: Traffic Sound, Los York's, Telegraph Avenue, Laghonia… In 1969, Los Mutables had their space-age inspired recordings released on MAG. An astonishing mix of outer-space sounds, raw fuzz guitars and groovy rhythms, recalling the best of the American garage groups of the time.

This 45 remains as their only record ever released and we are now happy to reissue it for the first time in its full glory.
