CRYSTALS

Line-up:

Carlo Degani (vocals, percussion)
Nanni Civitenga (guitar)
Marcello Todaro (guitar)
Giorgio Piazza (bass)
Giorgio Santandrea (drums)

With such an important line-up, it's strange that this group had such a short life. 
Crystals were a sort of supergroup composed by experienced musicians, former members of name bands like Premiata Forneria Marconi (Piazza), Banco del Mutuo Soccorso (Todaro), Raccomandata con Ricevuta di Ritorno and Samadhi (Civitenga), Alphataurus (Santandrea), and under the guidance of Paolo Tofani (Area and Electric Frankenstein) that composed all of their tracks.They recorded an album that was intended for release on Cramps label, but for mysterious reasons it never appeared, and has only been released on CD in the early 90's.
Needless to say, the record shows an excellent musicianship; the lyrics are sung in english, though the album has long instrumental parts; the musical style is closer to english prog even if we can hear some Led Zeppelin influences. A very influential band in the italian rock scene.
