Album: Songs in the Key of Life
. . .
While Songs in the Key of Life is always lumped in with the three (or four) albums that preceded it, it’s actually somewhat different, at least in its execution. While the 1972-1974 albums recorded featured the TONTO synth — and the guys who invented it, Robert Margouleff & Malcolm Cecil as the co-producers — as well as Wonder being responsible for the lion’s share of the instruments and vocals, Songs in the Key of Life was a more inclusive affair.
