Traffic Sound was a Peruvian rock band founded in 1967 by Manuel Sanguinetti, Freddy Rizo-Patrón Buckley, Jean Pierre Magnet, Willy "Wilito" Barclay Ricketts, Willy Thorne Valega and Luis "Lucho" Nevares. Manuel and Freddy had met in school and played in Los Hang Ten's, with the latter and his older brother Jose originally coming up with the idea of founding "Traffic Sound". Simultaneously, Magnet joined "Los Drags" as Barclay and Thorne played in "Los Mad's" with Nevares and, a while later, Thorne again playing in the short-lived Peruvian band "Ides of March". As noted earlier, they all met in the summer of 1967 and created Traffic Sound
The name was chosen because of their penchant for a traffic light, placed as a souvenir in the attic of the Rizo-Patróns house where they held their practices after a wild night in Lima.
