In the pantheon of legendary productions, 10cc’s “I’m Not In Love” ranks among the most respected tracks of all time. In fact, it reached a new generation of fans, thanks to its inclusion on the Guardians Of The Galaxy Vol. 1 soundtrack.
Consisting of minimal instrumentation, a lead vocal recorded in one take, and a bass-plus-music-box middle section, its arrangement was incredibly risky for a radio hit, even by modern standards. The element that glues the track together — keeping it transcendentally beautiful even after over forty years — is the song’s centerpiece: A painstakingly multi-tracked set of vocal loops, consisting of 48 tracks of voices per note over the chromatic scale. These multi-tracked vocals were then repeatedly bounced and re-recorded as eight-second tape loops that were then played via the mixing console, as sampling hadn’t even been dreamed up at that time.

Nowadays, the elaborate production technique for creating these vocals can be replicated much more easily using 21st century tools. All that’s required is a good microphone, a DAW, ample hard drive space, and an endless supply of patience. From there, it's quite straightforward.
