There is a short video clip for “Oblivious” at Sony’s Kalafina site, with new views of the Kalafina girls and some pretty animations. The video is 30 seconds long, and pans through near-still images of the vocalists with “Oblivious” playing in the background. Not sure if this is a preview of the full PV, or just a video promoting the single released earlier this year (as the main themes for the first three out of seven installments of Kara no Kyoukai). Thanks again to the amazing J. Uzuki for the discovery!
Click on the TV icon next to “Oblivious” to watch the video in a popup. I haven’t been able to open it with Firefox, but it works in IE.
