"Il Massacro di Brandeburgo numero tre in Sol Maggiore" is a fragment of Johann Sebastian Bach's third Brandenburg concerto.

During the recording sessions of the album, Capiozzo and Tavolazzi left the band temporarily (noticeably they are absent on "Diforisma Urbano", "Giro, giro, tondo" and "Caos (parte seconda)") only to come back some months later.

During these months in which they weren't in the band, the live album Event '76 was recorded at Milan's Università Statale.

Most of CD re-releases contain two bonus tracks: an interview with Stratos, Tofani and Fariselli after the "Event '76" concert and the "Are(A)zione" version of "L'internazionale".

From this album's tour, two posthumous concerts from 1977 were released: "Concerto Teatro Uomo" in 1996 and "Live in Torino 1977" in 2005.
