Gescom sources

I heard Adonis "No way back" in a recent EDMX podcast (22), and thought I recognized the riff and production from somewhere - D1 is probably my favourite Gescom track.

Does anybody have clues on the other tracks? The prog rock/fusion guitar lick in A1?

I added the tracks i knew on Discogs ages ago

C1 & 2 i couldnt put my finger on, sure i know 1 of them.
