Recorded ones, mostly orchestral, music from games (mix with some anime pieces is also OK), like the Night in Fantasia (and I liked only 2005 edition)... Some high quality stuff needed. Download links aren't necessary, I'll search for them, just the name of the concert event and some basic info about it. It'll be very appreciated. Thanks!

These two suggestions are anime-only:

Your icon suggests that you'd like Joe Hisaishi in Budokan - 25 years with Hayao Miyazaki concert from August 2008, if you don't already have it. I listened to it well over a hundred times. Mahler "Symphony of a thousand" sized choir and orchestra and great soloists.

I also liked the The Tokyo Philharmonic Orchestra / Suzumiya Haruhi No Gensou. Introduced me to Minori Chihara (and also includes one violin solo by Hiroaki Yura of Eminence).

And I thought nobody will reply... Thank you!
