Let's get it on...With those four simple words, Marvin Gaye transformed soul music. Here is the sensual touchstone for all of the erotic R&B and slow jams that followed, an album that embraces carnal delights and encourages romantic affairs. Rarely has an artist more explicitly and effectively spelled out his goals.
 
A lustful bookend to 1971's What's Going On, Let's Get It On took shape after the vocalist changed his approach while singing the classic title song. Originally intended to be a tune about moving on with life, Gaye turned it into a paean to sexual craving and consummate desire after taking notice of Janis Hunter, a studio visitor that ultimately became the Motown legend's second wife. The mood, feel, and tone of the record took off from there.
