This album has had over three decades to make an impact, and it says something for its staying power that, in the face of more recent, more generously programmed, and better mastered compilations of the duo's work, it remains one of the most popular parts of the Simon & Garfunkel catalog – which doesn't mean it isn't fraught with frustrations for anyone buying it. Its very existence is something of a fluke – in the spring of 1972, the five original Simon & Garfunkel albums, Wednesday Morning, 3 AM, Sounds of Silence, Parsley, Sage, Rosemary & Thyme, Bookends and Bridge Over Troubled Water, were still selling almost as well as they had in the 1960s.

Simon & Garfunkel's second album, Sounds of Silence, was recorded 18 months after their debut long-player, Wednesday Morning, 3 AM – but even though the two albums shared one song (actually, one-and-a-half songs) in common, the sound here seemed a million miles away from the gentle harmonizing and unassuming acoustic accompaniment on the first record. In between, there had been a minor earthquake in the pop/rock world called "folk-rock," which resulted in the transformation of their acoustic rendition of "The Sound of Silence" into a classic of the new genre, complete with jangling electric guitars and an amplified beat that helped carry it to the top of the charts…

Wednesday Morning, 3 AM doesn't resemble any other Simon & Garfunkel album, mostly because their sound here was fundamentally different from that of the chart-topping duo that emerged a year later. Their first record together since their days as the teen harmony duo Tom & Jerry, the album was cut in March 1964, at a time when both Simon and Garfunkel were under the spell of folk music…

Simon & Garfunkel quietly slipped Bookends, their fourth album, into the bins with a whisper in March 1968. They are equal collaborators with producer/engineer Roy Halee in a multivalently layered song cycle observing the confusion of those seeking an elusive American Dream, wistfully reflecting on innocence lost forever to the cold winds of change…

Bridge Over Troubled Water was one of the biggest-selling albums of its decade, and it hasn't fallen too far down on the list in years since. Apart from the gospel-flavored title track, which took some evolution to get to what it finally became, however, much of Bridge Over Troubled Water also constitutes a stepping back from the music that Simon & Garfunkel had made on Bookends – this was mostly because the creative partnership that had formed the body and the motivation for the duo's four prior albums literally consumed itself in the making of Bridge Over Troubled Water…

Simon & Garfunkel's first masterpiece, Parsley, Sage, Rosemary and Thyme was also the first album on which the duo, in tandem with engineer Roy Halee, exerted total control from beginning to end, right down to the mixing, and it is an achievement akin to the Beatles' Revolver or the Beach Boys' Pet Sounds album, and just as personal and pointed as either of those records at their respective bests…

Released to coincide with the duo's 2003 reunion tour, this two-disc anthology is no less than the fifth multi-disc compilation of the duo to appear in the CD era. Viewed coldly, it's a mercenary exercise, squeezing yet more juice out of one of the most valuable catalogs in the business…

Recorded on January 22, 1967, at Lincoln Center in New York, four of these 19 songs were on the 1997 Old Friends box set, but the rest were unissued until the 2002 appearance of this release. The duo performs acoustically, without accompanists (as was usually the case in their concerts), on a fine-sounding and well-delivered set that doesn't contain any revelations, but is nonetheless an excellent document of their live work as they reached their prime…

Simon & Garfunkel reunited on September 19, 1981, to perform a free concert in Central Park, New York City. This two-record set presents some of the duo's biggest hits in a live context, and also allows listeners a chance to hear what many Simon solo numbers could sound like in S&G mode.

The Simon and Garfunkel Collection: 17 of Their All-Time Greatest Recordings is the second compilation album by Simon & Garfunkel, issued outside of the United States in November 1981, 2 months after their landmark Concert at Central Park…

Old Friends is the second box set of Simon & Garfunkel songs, released in November 1997. The three-disc anthology collects most of the duo's best-known works, and also includes previously unreleased outtakes…
