The fifth track on The Works, “Machines (Or ‘Back to Humans’)”, came about as an idea by Taylor, with May collaborating and finishing it with him. Producer Reinhold Mack programmed the synth-“demolition” using a Fairlight CMI II Sampler. It’s sung as a duet between a double-tracked Mercury (singing in harmony with himself), and a robotic Taylor (using a Roland VP330 Vocoder). The instrumental remix of the song samples parts of “Ogre Battle” from Queen’s second album Queen II, “Flash” and Larry Lurex’s “Goin' Back” (in fact Queen (without Deacon) under a pseudonym). This song, along with “Radio Ga Ga” is some of the heaviest uses of electronics on the album.
