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".

[1] After a year of continued rehearsals and private shows and with the guidance of their manager, Jorge Manuel Vegas (b. Iquitos, Peru, December 20, 1944, d. Oslo, Norway April 17, 1987 ), the band tried their luck at Peruvian psychedelic emporium The Tiffany with great success and recorded his first album "A Bailar Go Go" in 1968 with label MAG.

In 1971 Braniff International Airways organized the first South American tour of a Peruvian band, and Traffic Sound was well received in demanding markets such as Argentina and Brazil.

At this point Willy Thorne left the band and was replaced by Zulu (Miguel Angel Ruiz Orbegoso) on bass and keyboards, with whom they recorded their last LP, "Lux".

The band held a memorable concert at the Teatro Segura in Lima together with the Contemporary Orchestra of Peruvian jazz pianist Jaime Delgado Aparicio in 1971[3] and disbanded in 1972.

In 1993, Traffic Sound members got together again for a concert at Muelle Uno, Miraflores, and launched new versions of their old hits, a London remasterization CD of "Virgin" for Europe.
