This is the best purchased I ever bought, on Amazon or elsewhere!For 23 CDs and a booklet about the entire discography of the artist Michel Polnareff for about 120 USD, this is a super bargain! The presentation of the item is superb, very detailed. The content is rich and full of surprises. As many of Michel's fans would know, each time the artist sings a song in a live concert, it is slightly different from the previous version, and sometimes it is an entire different re-arrangement.From a historical point of view, this CD set is a gift from the artist to his fans, so they can see his achievements in writing and arranging, directing the songs from the first song in 1966 to the most recent concert in 2016. wow a 50 year career!!! He is always in synch with what is going on with the world pop and rock scene, and maybe even one or two steps ahead!!!Thank you Mr. Michel Polnareff for giving his fans, myself included, such a precious gift!!!
