This is "Tune the Rainbow" originally off of "RahXephon Pluralitas Concentio O.S.T.". This is a live performance that included both Maaya Sakamoto and Yoko Kanno that was recorded for Japan Radio sometime early 2004.
I have simply edited a fade in and fade out with adobe premiere. I also edited the audio in adobe soundbooth with a filter called "Eq: Graphic" and used the setting "bass Management". I don't claim the song, or recording of it which was from another fan and then reposted on maayasakamoto.net. Based on what I know, this recording is public domain, and so is the edit I uploaded.
