Its got some of the best mixes I have heard. The Ayla mix especially was an unknown mix to me and brilliant. GK often use the less well known mixes and also often less well known tracks, its one of the reasons I like GK.
This album is as good as any of this type I have heard. 'Old tracks' it might be but if you like the tracks from that time then this album is really good, very well mixed and just brilliant.
