Great thread!
I bought Joni Mitchell, Blue with HDCD to compare to the original cd and the LP. Well my LP is too worn out to be fair but the HDCD beat the original cd without a doubt. This on I believe I could do in a blind test.
Some others in clude:
A Nod to Bob, a tribute album on Red House Records. Check their web site for this excellent and somewhat different tribute album. It's different because there are no big name stars just wonderful renditions of some great music.
Laura Love, You Ain't Got no Easter Clothes. This is a woman with a tale to tell.
A while back I also bought Manassas in HDCD so I could compare it to a pristine LP. Thanks for the reminder. I'll try it tonight.
