I have a habit of picking up any collection of music that was used in Jean-Luc Godard's films. There are lots of collections or compilations out there and it's impossible for me to choose the best one. All are great! So, reader, you have to take that in, that I'm just a super-fan with no critical judgment whatsoever on the subject matter of Godard's various soundtracks. There is a Japanese CD compilation that is excellent and I wrote about it here: http://toshberman.blogspot.com/2017/04/va-bandes-originales-des-films-de-jean.html
I bought "Histoire(s) de Musique" in Tokyo about ten years ago. For some odd reason, it's not difficult to find French New Wave soundtracks on CD in Japan. This collection put together by Universal Music is excellent. The one unique cut that the other's don't have is the song "Mao Mao" sung by Claude Channes and from the film "La Chinoise." This album covers all the Godard films from À bout de souffle ("Breathless") to Sauve Qui Peut (La Vie). So the time frame is from 1959 to 1980. The classic Godard years and the music are excellent. Martial Solal, Michel Legrand, the great Georges Delerue score for "Contempt" as well as Paul Misraki, Antoine Duhamel and Gabriel Yared. All wonderful soundtrack composers doing their best iconic work.
Also the CD has great text with nice photographs. Do get it!
