The most successful folk-rock duo of the 1960s, Paul Simon and Art Garfunkel
crafted a series of memorable hit albums and singles featuring their
choirboy harmonies, ringing acoustic and electric guitars, and Simon's
acute, finely wrought songwriting. The pair always inhabited the more
polished end of the folk-rock spectrum and was sometimes criticized for a
certain collegiate sterility. Many also feel that Simon,
as both a singer and songwriter, didn't truly blossom until he began
his own hugely successful solo career in the 1970s. But the best of S&G's work can stand among Simon's
best material, and the duo did progress musically over the course of
their five albums, moving from basic folk-rock productions into Latin
rhythms and gospel-influenced arrangements that foreshadowed Simon's eclecticism on his solo albums. Simon & Garfunkel's recording history actually predated their first mid-'60s hit by almost a decade. Childhood friends while growing up together in Forest Hills, NY, they began making records in 1957, performing (and often writing their own material) in something of a juvenile Everly Brothers style. Calling themselves Tom & Jerry, their first single, "Hey Schoolgirl," actually made the Top 50, but a series of follow-ups went nowhere. The duo split up, and Simon continued to struggle to make it in the music business as a songwriter and occasional performer, sometimes using the names of Jerry Landis or Tico & the Triumphs.
The Simon & Garfunkel story might have ended there, except for a brainstorm of their producer, Tom Wilson (who also produced several of Bob Dylan's early albums). Folk-rock was taking off in 1965, and Wilson, who had helped Dylan electrify his sound, took the strongest track from S&G's
debut, "The Sound of Silence," and embellished it with electric
guitars, bass, and drums. It got to number one in early 1966, giving the
duo the impetus to reunite and make a serious go at a recording career,
Simon
returning from the U.K. to the U.S. In 1966 and 1967, they were regular
visitors to the pop charts with some of the best folk-rock of the era,
including "Homeward Bound," "I Am a Rock," and "A Hazy Shade of Winter."
It was unsurprising, in retrospect, that the duo's
partnership began to weaken in the late '60s. They had known each other
most of their lives, and been performing together for over a decade. Simon began to feel constrained by the limits of working with the same collaborator; Garfunkel, who wrote virtually none of the material, felt overshadowed by the songwriting talents of Simon, though Garfunkel's
high tenor was crucial to their appeal. They started to record some of
their contributions separately in the studio, and barely played live at
all in 1969, as Garfunkel began to pursue an acting career.
