Blessed with what the New York Times described as a “beautiful countertenor,” singer Art Garfunkel has made an indelible mark on the music world as both a solo artist and half of the unrivaled Simon & Garfunkel. His most recent solo album was “Some Enchanted Evening,” a celebration of some of the 20th century’s greatest songwriters, such as Rodgers & Hammerstein, Irving Berlin, Harold Arlen, Antonio Carlos Jobim and George Gershwin. Garfunkel was originally revered for his Grammy-winning, chart-topping songs and albums with partner and fellow New York City native Paul Simon. Their greatest hits collection, which includes “Mrs. Robinson,” “Scarborough Fair,” “The Sound of Silence,” “The Boxer” and “Bridge Over Troubled Water,” among others, is the biggest-selling album ever by a duo.
