Sérgio Mendes, the pianist who gifted the world with the most famous version of the Brazilian classic “Mas Que Nada,” died on Thursday. Born in 1941, Mendes was a 20-year-old musician when he first arrived in the U.S. to perform at a historic Carnegie Hall concert that brought many bossa nova legends to New York in 1962. Two years after the show, Mendes moved to Los Angeles and never left the U.S. He also never abandoned Brazilian music, becoming one of the most significant ambassadors of bossa nova and samba around the world.^[[2] https://www.rollingstone.com/music/music-latin/sergio-mendes-mas-que-nada-legacy-1235097970/]
