I’ve found some HD both video and audio of artists I like on Youtube. Most are Japanese but that could be just because most of my favorite artists now are. I’ve found sever HD versions of Perfume concerts videos that are very good. Not quite BD quality but surprisingly good for something off Youtube.

Good luck on all that metadata since someone has to generate it.
