The Kalafina website has updated with a clip from the new single.
Visit www.kalafina.jp to listen to the sample and see a pretty new photo of Keiko, Hikaru, and Wakana.
The sample clip mp3 can be downloaded here – thanks to Kazado!
[EDIT Dec. 06 2008] A video clip preview has been added, with a different segment of the song. Thanks to Nodame for the shout!
