this double cd includes some great songs by amazing and very engaging duets. Do not listen to these CDs if by blues against because it makes very nostalgic. Once again a big thank you to the instigator of this project: Pascal Obispo, some songs are performed and which even he sings the song of Sir Francis Cabrel "off season" in a duet that I find beautiful. I really recommend this great product especially since it's for a great cause.
