Andrea was born in Rome in June 25th 1985. He began studying guitar at the age of 7, then moved on to the study of bass, which became his great passion from the age of 14.

In 2007 he began a collaboration with guitarist Marco Sfogli and joined “Marco Sfogli’s Band”, recording some tracks of his solo instrumental album called “There’s Hope” (Lion Music Records) and starting live activity with the band together with the keyboardist Alex Argento. In 2009 Astra released the second album “From Within” for the Finnish label “Lion Music Records”. Meanwhile Andrea joined the band “The Greatfire of Rome” as bass player and backing vocals, and released an EP of 4 tracks, but the band broke up some time later.
