Let's Get It On, Marvin Gaye - "I mumble things into the microphone," Gaye said. "I don't even know what I'm saying, and I don't even try to figure it out. If I try, it doesn't work. If I relax, those mumbles will finally turn into words. It's a slow, evolving process, something like the way a flower grows." On this album, those words turn into meditations on the gap between sex and love and how to reconcile them — an adult version of the Motown tunes Gaye had built his career on.
