Formula 3 (also spelled as Formula Tre) is an Italian prog-rock band, mainly successful in the early seventies. The group formed in 1969; produced by Lucio Battisti, they were the group that accompanied Battisti in his rare live concerts, and was originally made up of Alberto Radius (guitars and vocals), Tony Cicco (drums and vocals) and Gabriele Lorenzi (keyboards). Their first hit was the song "Questo folle sentimento", which ranked fifth at the Italian hit parade in 1970, and which was followed by a series of top 20 hits, notably "Io ritorno solo" (third at the Italian hit parade) and "Eppur mi son scordato di te" (second at the Italian hit parade), all composed by the same Battisti.
