It's true, it's very similar! but there are parts in the song of the shrek game, notably from 00:00 to 00:25 and 01:01 to 1:14 which is very similar to its music: https://www.youtube.com/watch?v=ncWwkhnL0Sc&t=31s (the begging) and https://www.youtube.com/watch?v=I4vR4Z2YNT8 (at 1:36) or this bgm : https://www.youtube.com/watch?v=4Zfz8Ph-9ng&t=245s
it looks like it's the same type of music but it doesn't seem to be celtic ...
What do you think ?
Yes, it's hard to include it into a specific style. It's like the musical works of John Williams or Jerry Goldsmith, that people use to call "movie music" or something like this.
I know it's kind of offtopic, but there's a few disks I'd like to use this thread to recommend. I love prog-rock and similar styles because musicians from that genre use to be fantasy and sci-fi lovers, and often have done conceptual works in which all the songs of the record form a complete story, as if it was some kind of book or movie but using only music and lyrics to tell the story. We could say that prog-rock is to music what jrpgs are to videogames
Two records I've enjoyed for its storytelling are, for instance:https://www.youtube.com/watch?v=TNhtAh3U_sc
This one would be some kind of ambient-newage-electronica mix. It tells a story of a fish-shaped starship found in orbit around Saturn, and the ancient encoded writings that researchers find inside which tell of the origins of humans in another planetary system.https://www.youtube.com/watch?v=TBvjjzAkz-I&list=PLxzSZG7g8c8zoUeLh9L8deFQT019KIkwq
This other one is more prog-metal oriented, in the vein of Dream Theater and the likes. Tells the story of a group of people from different periods of history who find themselves transported to a castle from which they have to manage to exit alive and find out who took them there.
This post has ended being a little longer than I thought, sorry
