To learn more about her, I let you read the article of wikipedia which is very well done (who says I'm lazy?).
Some of my favorite songs, that just give a little taste of her talent:
Dommage Que Tu Sois Mort (1968)Comme A La Radio (1970)
Lettre A Monsieur le Chef de Gare de la Tour de Carole (1970)
L'auberge (1972)
And to not forget her recent work:
Je T'Aime Encore (2001)
