Sérgio Mendes is a Brazilian artist who started his career playing in nightclubs in the 50's. He mainly plays Bossa Nova, a jazz-inflected derivative of Samba, which began booming around that time. This song called Más Que Nada (More Than Anything) became popular with it's catchy chorus. It was remade in 2006 featuring the Black Eyed Peas. Enjoy listening.
The new version featuring the Black Eyed Peas:
I also want to add a couple of other songs by him. In relation to class, I like how a genre, in this case - Samba, can become a type of root for other genres to develop, transform and/or progress. It is interesting how genres and sub-genres can use songs, beats, melodies, etc. as precedents and reform them into something progressive.
