A delightful concept album in the best sense of the word, I Remember Yesterday found Summer and her key collaborators Giorgio Moroder and Pete Bellotte creating a tour through the history of 20th century popular dance music through the lens of disco, all within the space of 35 minutes. The salutes to big band and soul and r&b were certainly great but the killer touch was the final number representing the future: “I Feel Love.” An all-electronic anthem aside from Summer’s voice and kick drums by Keith Forsey, it was a smash hit that became a standard.
