A lot of interesting songs in this thread
Here's another favourite from me, Gong's Gazeuse!. Those who know Gong will know that it was a highly talented and drugged up psychedelic/space rock outfit originally led by Daevid Allen, but with a wealth of musicians visiting the line-up. In the mid-90s, Daevid claimed a wall of force was preventing him to go on stage and he decided this meant it was time to quit the band for a while. Drummer Pierre Moerlen took over and made it a fusion outfit.
The first album with this line-up contains talents like amazing guitar virtuoso Allan Holdsworth, flautist/saxophonist Didier Malherbe and bassist Franciz Moze. The album is a little special from it's extensive use of percussion instruments like marimba and vibraphone.
Percolations is the album's slowest piece and actually reminds me of an underwater world in a video game.
Esnuria is more representative of the album, though!
