Xenon appears to be a group of musicians and producers coordinated by Marzio Dance, who was the DJ at Xenon, a Florence (Firenze) discothèque.
Song titles vary from release to release, sometimes being prefaced with "Xenon" and other times not. Artist names are sometimes inconsistent, as well, with Xenon and/or Marzio Dance credited for the same title on different releases.
There is also a Xenon label, on which some of these releases appeared, and which sometimes uses "Xenon Production" pseudo-credits.
