Traffic Sound was a Peruvian rock band founded in 1967 by Manuel Sanguinetti (vocals), Freddy Rizo-Patrón (rhythm guitar), Jean Pierre Magnet (sax), Willy "Wilito" Barclay (lead guitar), Willy Thorne (bass) and Luis "Lucho" Nevares (drums). Freddy and Manuel had met in school and played in Los Hang Ten's. Freddy and his older brother Jose originally thought of founding "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.
