Nebula was an open ensemble founded by Gianluigi Gasparetti (aka Oöphoi) with Mauro Malgrande, Klaus Wiese, Lorenzo Pierobon, and Enrico Cosimi (aka Tau Ceti). Their first album, Genesis, was released in 2002. In 2003 two new members had joined the group, Mathias Grassow and Geert Verbeke. In the same year Nebula released a second album, The Path of White Clouds.
Every musician contributed freely to the music but the final result was entrusted by Gianluigi Gasparetti.
