Ah finally, it took some time to get through them all. As you can see I consider most of ARP albums to be quite equal in quality, usually it's as little as 1 songs that makes the difference. I was quite suprised actually how much I enjoyed his discography overall, I was pretty familiar with all the albums up to Mystica but after that I lost my interest, as it seems most of the albums released after is just as much fun as the other ones.

If you are unfamiliar with ARP my recommendation is that you start with a live album by them, those are always good fun and if you like it then check out the studio albums.
