When he first emerged as a singer, Roberto Carlos was nicknamed the Elvis Presley of Brazil. Fifty years later,  he is more often described as “the Frank Sinatra of Latin America”. No Latin American has sold more records than Roberto Carlos, who  performed on Friday and Saturday night at Radio City Music Hall, part of a North American tour that wraps up a year’s worth of events commemorating half a century as a recording artist.  He is considered one of the most influential artists in Brazil during the 1960s, being cited as a source of inspiration by many artists and bands up to the 1980s. Roberto Carlos left Jovem Guarda in 1968, changing direction to appeal to a wider audience. Moving to romantic ballads,  he became an international star, gaining popularity, awards and breaking musical sales records. During the 1970s, he was also a regular performer on both Brazilian and international television variety shows. He is known to every Brazilian simply as “the King”.
