The band's best known lineup featured Sylvain on vocals, Francois Cossette (guitar), Denis Lavigne (drums), and Jean-Francois Houle (bass).
After establishing a local reputation for their live act, the band received a FACTOR award in June 1988.
With Sylvain's brother Francois joining the lineup on guitar, the band recorded their self-titled debut album Paradox at Studio Victor in Montreal in 1988.
Produced by Pierre 'Baz' Bazinet (who was best known for his work with other Canadian acts including Luba and Boulevard), much of the album was co-written with Sass Jordan whose own star was rising at the time.
After a final concert in 1991 at the Spectrum in Montreal, the band broke up and Sylvain continued his career as a French solo artist.
