The duo's often rocky relationship led to artistic disagreements and their breakup in 1970. Their final studio album, "Bridge over Troubled Water", was released that year and became their most successful, becoming one of the world's best-selling albums. After their breakup, Simon released a number of acclaimed albums, including 1986's "Graceland". Garfunkel released solo hits such as "All I Know" and briefly pursued an acting career, with leading roles in two Mike Nichols films, "Catch-22" and "Carnal Knowledge", and in Nicolas Roeg's 1980 "Bad Timing." The duo have reunited several times, most famously in 1981 for The Concert in Central Park, which attracted more than 500,000 people, one of the largest concert attendances in history.
