The song, inspired by a experience during an excruciatingly long traffic light at New York City’s Eleventh Avenue, became a crucial hit for The Four Seasons.

Jennifer Warnes, bassist Roscoe Beck and engineer Billy Youdelman share how the unlikely Leonard Cohen cover—and the album around it—came to be a hit.

“To me, those Charlie Rich sessions were so special,” recalls engineer Lou Bradley.

“You’ve Lost That Lovin’ Feelin’” was also one of the most perfectly realized examples of the “Wall of Sound” technique that Phil Spector refined.

The sublime studio concoction of “She Drives Me Crazy” involved a trip to Minneapolis, that signature falsetto and a snare hit that rings to this day.

27 years after their duet “The Boy Is Mine” ruled the charts, Brandy and Monica finally played a co-headlining tour this past fall—and Demetrius Moore was behind the FOH desk to make sure it sounded perfect.
