Getz/Gilberto is a 1964 jazz-bossa nova album by American saxophonist Stan Getz and Brazilian guitarist João Gilberto, featuring composer and pianist Antônio Carlos Jobim.  Its release helped fuel the bossa nova craze in the United States and internationally, becoming the first Grammy Award-winning album from non-American artists.  It brought together Stan Getz, who had already performed the genre on his LP "Jazz Samba", João Gilberto (one of the creators of the style), and Jobim, a celebrated Brazilian composer (and also one of the main creators of the genre), who wrote most of the songs in the album.
