Let’s ask it another way, where can you great concerts other than blueray. You can stream a lot of great content. The Zidoo has an android OS and you can get geat apps for concert streaming. They won’t have the dynamics of a blueray but thre are tons of content, they add new content all the time, and its cheap:
1) Qello Stingray
2) Plex (has various concert channels that are FREE)
3) Berlin Philharmonic
4) Tidal (streams videos of concerts)
5) Nugs.net
