Umberto Antonio Tozzi (born 4 March 1952) is an Italian pop/rock singer and composer, born in Turin. His most internationally famous songs are "Gloria" and "Ti Amo".
In 1968, at the age of 16, Umberto Tozzi joined 'Off Sound', one of the many groups that performed in small venues around Turin. In Milan, he met Adriano Pappalardo, with whom he formed a 13-piece band and began a large-scale Italian tour.
In 1974 Tozzi had his first success as a songwriter, with the song "Un corpo, un'anima" ("One Body, One Soul"), co-written with Damiano Dattoli and performed by Wess and Dori Ghezzi. It appeared on Canzonissima, an Italian music programme running from 1956 to 1974.
