I've only heard of it being classified as Trance. Yes, I know there was a Look To The Sky (Trance Mix), but it's less like basic Trance than the original. The remix seems a little closer to Cyborg Trance (which I don't call a "real" genre, but it's used in IIDX).
Original:Trance
True Color: Trance (it seems more of a rearrangement than a remix to me)
Trance: Cyborg Trance
Cyber True Color: Cyborg
Reiko's Theme(7 minute one): It feels like synthetic trancey rock.
Kors K remix: I have no Idea.
Simple question: what genre of ELECTRONIC MUSIC does Look to the Sky fall under?
There is no electronica. It is a term created by the American media to define 'McTrance'.
On that note, if Cyborg Trance is real, so iis Human Sequencer o____o;;; Look To The Sky anything in generally Trance, I guess you might say Progressive Trance for True Colour and Cyber True Color kind of sounds like it would be Tech. Reiko's theme sounds like it would be somewhere near Electroclash (though I'm probably WAY off on that one). Never heard of Kors K.
Google 'Ishkur's Guide to Electronic Music' and go to the di.fm link for any genre needs. It's big but you should find anything you need there.
