Springsteen expanded the folk-rock approach of his debut album, Greetings from Asbury Park, N.J., to strains of jazz, among other styles, on its ambitious follow-up, released only eight months later. His chief musical lieutenant was keyboard player David Sancious, who lived on the E Street that gave the album and Springsteen's backup group its name. With his help, Springsteen created a street-life mosaic of suburban society that owed much in its outlook to Van Morrison's romanticization of Belfast in Astral Weeks. Though Springsteen expressed endless affection and much nostalgia, his message was clear: this was a goodbye-to-all-that from a man who was moving on. The Wild, the Innocent & the E Street Shuffle represented an astonishing advance even from the remarkable promise of Greetings; the unbanded three-song second side in particular was a flawless piece of music. Musically and lyrically, Springsteen had brought an unruly muse under control and used it to make a mature statement that synthesized popular musical styles into complicated, well-executed arrangements and absorbing suites; it evoked a world precisely even as that world seemed to disappear.
