"Supplicio" is a sound clip on the Head soundtrack album featuring audio clips from the film. It begins with a sting from the musical score by Ken Thorne, followed by the sound of a rocket, which echoes into dissonance and crossfades with the sound of wind. An unknown actor, intended to be the voice of God, narrates, "Quiet, isn't it, George Michael Dolenz? I said, ..." The track abruptly stops here and leads into the next song on the album, "Can You Dig It".
The word in the track's title, "supplicio", is Italian for "punishment". The scene from the film, which this track references, finds Micky Dolenz lost in the desert, perhaps as a form of purgatory, whereupon a tank full of Itlaian soldiers pulls up and surrenders to him.
