Just a heads up for those who may not be aware already: Kajiura will be doing the music for the upcoming Kara no Kyoukai movies. She will also be doing the ED themes, and her project for creating the 7 ED themes (one for each of the chapters) will be under the name Kalafina. It seems this is sort of like her FictionJunction project, where she works with different singers for different songs, except this is limited to her work on Kara no Kyoukai.
The first ED is called "Oblivion" and you can hear a sample of it on the Official Kalafina site. Sounds very nice and typically Kajiuran. ;) The first 3 ED themes will be combined into one single under the title Oblivion and will be on sale 2008/01/23.
