Le Orme is one of the longest lasting and best known Italian progressive rock bands. The band was formed in Venice in 1966 by Aldo Tagliapietra (voice, guitars), Nino Smeraldi (guitars), Claudio Galietti (guitar and bass) and Marino Rebeschini (drums). Their first album, Ad Gloriam, was released in 1968. From their psychedelic and beat roots, they moved into increasingly sophisticated musical structures. Their 1973 album Felona e Sorona is widely regarded as one of the top albums in Italian progressive rock. By this time the band consisted of Tagliapietra (mostly on bass, with some guitar) along with keyboard player Tony Pagliuca, and drummer Michi dei Rossi. As the 1970s waned, Le Orme, like most progressive bands, shortened and simplified their music. Starting in the late 1990s, a resurgence of interest in progressive rock led the band to revisit elements of their classic style, and the albums Il fiume (1999), Elementi (2001), and L'infinito (2004) have been received favourably in the progressive community. 1966-67 Aldo Tagliapietra (vocals, guitar) Nino Smeraldi (guitar) Claudio Galieti (bass) Marino Rebeschini (drums) 1967 Rebeschini replaced by: Giuseppe "Michi" Dei Rossi (drums) 1968-70 Aldo Tagliapietra (vocals, guitar) Nino Smeraldi (guitar) Antonio "Toni" Pagliuca (keyboards) Claudio Galieti (bass) Michi Dei Rossi (drums) 1969 Galieti quits, De Rossi temporarily replaced by Dave Baker (drums) 1970-75 Aldo Tagliapietra (vocals, bass, guitar) Toni Pagliuca (keyboards) Michi Dei Rossi (drums) 1975 enters: Tolo Marton (guitar) 1976-80 Marton replaced by: Germano Serafin (guitar) 1980-82 and again 1986-1990 Aldo Tagliapietra (vocals, bass, guitar) Toni Pagliuca (keyboards) Michi Dei Rossi (drums) 1996-2000 Aldo Tagliapietra (vocals, bass, guitar) Michele Bon (keyboards) Francesco Sartori (keyboards) Michi Dei Rossi (drums) 2001 Sartori replaced by Andrea Bassato (keyboards, violin)
