/jp/ - Otaku Culture

If you like trance I highly recommend checking out Levo Lution. Hell, even if you don't like trance or any electronic music I'd still recommend giving them a listen. Their earlier stuff is Ragnarok and Final Fantasy arranges but they have 2 (or 3) touhou arrange albums, their opus being Skyrise (in my opinion). Here's the opening track from the album:

Transparent Metropolis of the Sky High - http://www.youtube.com/watch?v=xlNfM4ndRwk

Wonderful uplifiting trance and no vocals. Can make you feel chilled out or make you feel awesome. If /jp. does ever make an essential Touhou Albums list, this one has to be there under trance section.
