Floating Cities by Kevin MacLeod
It is the future? It certainly sounds like it... What would I use this for? Probably a video game with non-action gameplay. Certainly a montage of some futuristic film... or maybe one of those sandwiched scenes where a person is walking in the rain, but you don't get any of the sounds of the actual rain... just this piece. No dialog, no voiceover, just walking. Do they have a name for those scenes? They must. You can download this in uncompressed format here.
