Track for track, this is Simon & Garfunkel's best album. By 1968, Simon had shed his more precious tendencies as a songsmith. Meanwhile, the duo and coproducer/engineer Roy Halee had become adept studio technicians. "America" and "Mrs. Robinson" displayed the kind of sonic breadth that would flower even more fully two years later with "The Boxer" and "Bridge over Troubled Water." Bits of whimsy ("Punky's Dilemma," "At the Zoo") and melancholy ("Old Friends," "A Hazy Shade of Winter") complete this autumnal album. (The 2001 reissue adds two bonus tracks, including a demo of "Old Friends.") --Steven Stolder
