Sounds awesome! *_* I love Filter, Jane's Addiction, and Rasputina! ^_^ I'm sure the rest of the artists on there will be uber awesome, too. XD I mean, the article does say Yoshiki was involved in both the music in the movie and the soundtrack music! ^_^ Though they mis-spelled his last name ("Haysahi"? XD Here's hoping that was just a typo. o.o).
I had heard musicians from Nine Inch Nails would be involved in this, too, but I guess that was just a rumor. o.o Unless one of the people listed there was also in NIN at some point. XD
