5.1 Music disks


Looking for some suggestions on good quality music 5.1 blu-rays.
I already have Jeff Beck at Ronnie Scotts, K.D. Lang Live at London, and a few others, but not a real wide selection.

What would you recommend as well recorded 5.1 music blu-rays or DVDs...
Thanks in advance!

Just wanted to say isn't that jeff beck live at ronnie Scott's fantastic. What a group's of players he has assembled there. 
I only have a stereo system but the following BluRay discs sound the best to me:
Sgt. Pepper, Chicago Quadio, Stevie Wonder - Songs in the Key of Life, The Doors - Perception, anything remastered by Steven Wilson (Yes, Tull, XTC, etc), Led Zepp hi-def, and the new Japanese release of Miles Davis - Bitches Brew should get you started.....and, as a bonus, double as a stress test for your bank account.
