The album dealt with different issues like conservation of nature, science fiction and spirituality.  The tracks scan the fields of Neo Prog and Symphonic Rock with comfort, most of the guitar melodies are fantastic, while Eloy Fritsch seems to be another talented keyboard wizard, torturing his minimoog synthesizer with easiness.  Lots of shifting moods and diverse textures guarantee another enjoyable release by the band.

10,000 Anos Depois Entre Venus e Marte: 10.000 Anos Depois Entre Vénus e Marte (In English: "10,000 Years Later Between Venus and Mars"), is a progressive rock album, by Portuguese musician José Cid, released on 15 May 1978.

Clearlight (French band): Clearlight is a French progressive rock band from the 1970s, although their best known work was produced in England, and released by a major British record company.  While progressive rock is an appropriate overall genre for the band, much of their work delves into other genres including psychedelic music, jam band music, symphonic rock, space rock, jazz fusion, and new-age music.

Atmosphere (Eloy Fritsch album): Atmosphere: Electronic Suite is an album by Eloy Fritsch, a keyboard player known for his work in the progressive rock group Apocalypse.  As a solo artist he creates cosmic electronic music.  The closest comparison would be probably Vangelis, if considering his early work, which included many analogue instruments.  Nevertheless, Fritsch has found his own style within melodic Electronic music framework.  The opus reveals once again Fritsch’s ecological convictions: he presently defends the virtues of the gas envelope that allow everyone to live on Earth: the Atmosphere, a theme which is carried over to the album art featuring a cloud formation juxtaposed with outer space.  The music is sweeping, majestic, and at times orchestral.  It moves from clear melodic themes that are somewhat earthly to the more experimental out-there stuff in the middle of the album, only to return to anthemic epicness by the end.
