Free Wave System is a jazz/fusion quartet from Turin, Italy.
While there is not a lot of information available about them,
it seems they formed in the 1970s from the ashes of a
group called Assoluto Naturale, who were more of a
traditional progressive rock band influenced by the usual
suspects, PFM, Banco, and the like.
That band featured vocals, and performed early incarnations
of Free Wave System songs, but Free Wave later decided
to be an instrumental band. Brothers Luca and Enrico Morandi
left this band and joined bassist Luciano Devietti and saxist
The band claims to have been most influenced by Perigeo,
and I would say they compare very well to other Italian
jazz-prog outfits such as Arti Mestieri, Bella Band, Etna,
