Dario Argento had used the Italian rock band Goblin to provide the musical scores to two of his previous films, Deep Red (1975) and Suspiria (1977). Goblin helped define the sound of 70's horror fims and giallos. The group had disbanded in 1980, but three of the band's members—Claudio Simonetti (Roland Jupiter-8, Roland Vocoder Plus, Minimoog, Piano, Electric Piano, Oberheim DMX Digital Drum, Roland TR-808, Roland MC4 Computer), Fabio Pignatelli (Fender bass normal and fretless), and Massimo Morante (Electric and Acoustic guitar)—reunited at Argento's request to work on Tenebrae. The result is a synth-driven rock out that is an essential Italo Disco time capsule as well. Some may recognize the main theme sampled in Justice's "Phantom", which to me is essentially a remix. Nice try guys.
