Best album of Vangelis:

1.- Odes. (No comment. Just run and get it in NO remaster release please.)
2.- the B side of Heaven and Hell is just perfect and original like not much else in the music history.
3.- Mask is an instant KO! The most grandioso, adorable. In style, like, say Carmina Burana. Pity it lacks a bit of the electro-feeling but you will be knocked out and won't be able to stand up from then on...!
4.- Soil Festivities. Meditative journey inwards. The deepest thing ever...
5.- Direct. The technocratics father's rebirth...
6.- City. Just great, fresh and new again.
7.- 1492. Grandioso. His last great album.
8.- The A side of Spiral (3 tracks) is a blast and a typical example of the 70's electro discoverings.
9.- Earth. Ancient, original, energetic, versatile. A bit flower-power era but the good is that he was dare enough to energetise it all with electro-spice.
10.-Opera Sauvage. Emotional and dramatic like never. Bit underrated maybe due to the accent only to the dramatic melodies instead of the technochratics developements.

Good albums:

1.- China. (Himalaya is one of his greatest)
2.- Albedo 039 (2 Instant mega classics there)
3.- L' apocalipse des animaux. The birth of ambient! Just calm, haunting...
4.- Dragon. Try getting it on CD! A very "offtopic" from the later releases. Jazzy, flower-power, prog.
5.- See you later. With some excellent tracks as: Multi track suggestion. Look for the rare version with BONUSES! I have it.
6.- Short stories. (with Jon Anderson of Yes.)
7.- Friends of Mr. Cairo. The 1st. and last track is the thing. (with Jon Anderson of Yes.)
8.- Private collection (with Jon Anderson of Yes.It's not a sampler).
9.- Page of life. (with Jon Anderson of Yes once again.)Superb tracks there: Money, Be a good friend of mine... Watch-out: US-CD has different tracks: the best song is missing and it opens with a different track. Strange.. Also look for the Another Page of life with 5 rare different tracks!
10.- Mythodea. There are some good movements developing but never building up. Album of ever-promising next minutes which never satisfies the expectation. But the main theme at the end is simply shocking!!...

Meditative, experimental (nonmusic) albums which are hard to rank due to lack of "music":

1.- Beabourg
2.- Invisible connections

Boring albums, not bad though:

1.- Ignacio
2.- Hypothesis (early 1971 release, space-jazz, organs, drums, 70's psy-prog.)
3.- Voices (with some good tracks though)
4.- Oceanic (with some good tracks though)
5.- Le Féte sauvage (with some good tracks though)
6.- Chariots of fire. (with 1-2 good tracks though but almost no electro-feeling)
7.- Custeau
8.- Mounty on the Bounty (it will disappoint you if you grab it)
9.- Cavafy
10.- Bitter moon
11.- Nurenberg
12.- L'Arbre de vie
13.- Missing
14.- Francesco
15.- Sex power
16.- Blade Runner. Please notice: I've met this CD first and saw the movie LATER. Without having seen the film, I've found this CD boring and ranked it here. The movie is absolutely one of the best ever and the soundtrack is just perfect but not as a standard Vangelis serial-release. It's boring me and I find it very uninteresting, little kitschy and very lack of the electronic-progress. It's a background music, a soundtrack and not a stand-alone something. I know, Blade Runner fans like I am (!) defend their beloved and will attack me. I'm sorry to say, but I've had almost 30 years to get deeply involved into this CD but I find almost nothing interesting there and I can't tell any better despite of my best intentions, sorry... (Hearing the sax first time was an immediate disappointment...) Interesting thing is, that this album has sooo many different releases, that I can't even follow after. Different tracks, versions... OK, I think to grab the official 3-CD box is the best. The other 2 CD is new material and were only inspired by the movie. A little filler but a must.

Worst Vangelis albums (what not necessarily means that one can't listen or for heaven's sake, enjoy it, but somehow I had to create a ranking and self-explanatory not every releases can fit to the highest standard even if it's the fabulous Vangelis work of art:

1.- Alexander.
2.- Antarctica (Hmmm... not that soo very bad, but...)
3.- Rhapsodies (The last track is great)
4.- Fais Que Ton Rêve Soit Plus Long Que La Nuit (with French singing all along, like on a camp-fire.)
5.- El Greco. (Filler, bad, plastic electro sonic timbres.)

Once again: the ranking is a matter of subjective feeling altough I'm very much into the electronic music since my childhood and I make music also. So you can maybe take a little account on me because I even have a bit deeper innersight as a pro-synth collector and user. Pity, the great Vangelis doesn't pioneering the electronic music anymore. He used to be as original, path-finder as: J-M. Jarre, Kraftwerk, Tangerine Dream but after having the early years passed, he just relies on his good old equipments and mastery. In every 8-10 years he renews his equipments and the ways of approach to them and that certain albums brings us something new side of Vangelis. Pity, his last change, renewing can be pointed at ca. the album of "City" which was 20 years ago. Hm... Everybody loves Vangelis and we all wish all the best renewing for him and wait for a new work of art.
