Takeharu Ishimoto: Before Crisis, Dissidia?

I’ve recently fallen in love with Mr. Ishimoto’s work, and I already own Subarashiki kono Sekai / The World Ends With You and Crisis Core: FFVII soundtracks. I’m trying to find some others… Hopefully Before Crisis FFVII (I own only the "Rebirth" track, that was on the sampler album) and Dissidia (again, I own only the sampler tracks.)

Thank you for your time!
