Hey folks
After reading Alan's blog on the value of surround sound music, I am interested in getting a music bluray for my brother (who has 5.1).
Any recommendations? Safe bet = acoustical folksy.

Needs to be able to play on an older bluray player.

PS...I'll be taking recommendations seriously myself (PS3 is my current player, which I understand won't work with some options- at least not in full capacity).

As always, thank you in advance.
