I recently came accross an upcoming artist I had never heard of before who goes by the name of "Naibu". In short, he is an underground producer who makes some amazing futuristic / fantasy style music. The sound of his tracks is really melodic and atmospheric, and they have some great beats to them as well. Though I can't put my finger on specifics, his stuff totally reminds me of music I have heard from various fantasy / sci-fi anime soundtracks.
To listen, some of his tracks are on his myspace ( www.myspace.com/naibudnb ) IMO, the most noteable tracks are "Aki" and "It Took A Long Time". I thought they were absolutely beautiful and I was completely mesmerized by these tunes! I never knew that there was a specific "genre" for this type of music, much less there are people that actually produce it!
