Piero Marras, born Pietro Salis on September 16, 1949, in Nuoro, Italy, is a renowned Italian singer-songwriter and multi-instrumentalist. He is celebrated for his contributions to Sardinian ethnic music. Marras began his musical career in Nuoro with local bands such as the Jollymen and I Granchi. In 1967, he moved to Cagliari and joined the band Nobili before founding the Yamaha. By 1971, he was a keyboardist and singer for the progressive rock band Gruppo 2001, releasing several singles and an LP before leaving in 1974 to pursue a solo career.

Initially, Marras released three albums with EMI featuring songs in Italian. He later shifted his focus to songs in the Sardinian language, releasing albums like "Abbardente," "Funtanafrisca," and "Tumbu," which drew inspiration from Sardinian culture and folk sounds. His music often blends cantautorale influences with traditional Sardinian elements.

Marras has also contributed as a songwriter for other artists, including Andrea Bocelli, for whom he wrote "A volte il cuore." He penned several tracks for Tazenda's debut album in 1988 and made history with his song "Mama," the first Sardinian-language track presented at the Sanremo Music Festival.

In 1992, Marras embarked on the Tour Andalas, showcasing Sardinian music and culture. He performed at the Vatican's Christmas Concert in 2000 and was awarded the Ignazio Silone Prize in 2003 for the cultural significance of his Sardinian-language songs. Throughout his career, Marras has released numerous albums, including "Fuori Campo," "Stazzi Uniti," and "Ali di stracci," and continues to be an influential figure in Sardinian music.
