In 1974, Les Variations became the first French rock band to sign with an American label, Buddah Records, while creating a more exotic and unique style reminiscent of their North African roots.
In the summer of 1975, after the band's national tour of America in support of their charted album, Robert Fitoussi choose to branch out on his solo career as F. R. David.
Les Variations reformed at their Cincinnati band house and studio with Tobaly, Bitton and Morris and the addition of American singer Carl Storie and bassist/singer Albritton McClain.

Over their ten years on the road they toured with many major acts of the era, including: Bachman–Turner Overdrive, Kiss, The Jimi Hendrix Experience, Cream, Yes, Guess Who, Taste, Queen, Uriah Heep, Rush, Kraftwerk and Aerosmith, to name a few.
