Music

Gilberto Gil.
Vinicius Cantuaria.
Chico Buarque.
Caetano Veloso.
Tom Jobim took a poem from Vinicius de Moraes and turned it into a song called "A felicidade". I don't know much else about these two artists but this song is quite nice.
Harmonium: a quebecois group.
Offenbach: the quebecois rock and blues group not the composer.
Pink Floyd
Vangelis
Kitaro
Vivaldi
Debussy
and other composers.
