Sinatra sings The Girl from Ipanema. 
For me, a strictly personal view id that it was theintroduction of the Bossa Nova musical style from Brazil that brought a fresh musical style to offset the incessant noise and banging of Rock and Roll ( which was helpful when chasing co eds in college. )
Antonio Carls Jobim was the most prolific composer, pianist and guitarist of the Bossa Nova movement. Here he is with Frank Sinatra singing about The Girl From Ipanema- a sultry vision of loveliness strolling along the beachfront.
