I know that some, if not all, of the music on that mix isn't actually BY him. And I don't think he really altered the songs in any way OTHER than just slowing them down. At least to my ears it sounds like that's all he did. The songs that I could identify are Modular Mix, by AIR, from their Premiere Symptomes album. That plays at the very beginning. Then following that is Channel 1 Suite, by Cinematic Orchestra, from their Motion album. At 25 min. 30 sec., Worksong by Tosca, from their Opera album, starts playing. And there's another song by someone else that finishes the set which I wasn't able to remember who it was by.
Definitely check out Tosca if you are into downtemp. Their second album, Opera, is what I consider to be one of the best downtempo works ever. I remember one review saying something to the effect of the album being like the smoke rising from an after-sex cigarette on a foggy night.
