The album was produced, arranged, and almost entirely composed by Brian Wilson with guest lyricist Tony Asher. It was recorded largely between January and April 1966, a year after Wilson quit touring with his bandmates. His goal was to create "the greatest rock album ever made"—a cohesive work with no filler tracks. It is sometimes considered a Wilson solo album and a refinement of the themes and ideas he introduced with "The Beach Boys Today!" (1965). Lead single "Caroline, No" was issued as his official solo debut. It was followed by two singles credited to the group: "Sloop John B" and "Wouldn't It Be Nice" (backed with "God Only Knows").
