Simon & Garfunkel were an American folk rock duo consisting of singer-songwriter Paul Simon and singer Art Garfunkel. They were one of the best-selling music groups of the 1960s and became counterculture icons of the decade's social revolution, alongside artists such as the Beatles, the Beach Boys, and Bob Dylan. Their biggest hits—including "The Sound of Silence" (1964), "Mrs. Robinson" (1968), "Bridge over Troubled Water" (1969), and "The Boxer" (1969)—reached number one on singles charts worldwide. They won 10 Grammy Awards and were inducted into the Rock and Roll Hall of Fame in 1990.
