Best Jazz and Rock & Roll HDCD CDs

Beck's Midnite Vultures is HDCD as well and it sounds excellent. I'm not a fan of his music at all but that one is a solid listen. I would also second the David Grisman catalog, great music and great recordings. I would also recommend Ron Sexmith-Blue Boy and Paul Simon-You're The One. Neil Young-Silver And Gold is quite good also come to think of it. It's neat to hear everyone's suggestions as there are quite a few discs that aren't labled HDCD. Just picked up an Arcam CD23T partially because I have a solid collection of HDCD's and couldn't bear to not have the proper encoding. Fortunately it turned out to be a great player overall and does some things nicely that my other digial rig was not as good at. Keep em' coming...

Jazz-From the Age of Swing/Dick Hyman,on Reference Recordings.
excellent sound quality IMhO.'Rock'-Searchin for a Rainbow,Marshall Tucker Band,on Shout Factory.Decent sound quality.

Neil Young's Live at Massey Hall....great in HDCD and my best find of 2007

Here's what's in my (eccentric) collection:
Mahavishnu Orchestra - The Lost Trident Sessions (HDCD)
Xtc - Apple Venus Vol 2 - Wasp Star (HDCD)
Isham, Mark - Miles Remembered: The Silent Way Project (HDCD)
Mitchell, Joni - The Hissing of Summer Lawns (Remastered - HDCD)
Sigur Ros - () (HDCD)
Camel - Rajaz (HDCD)

I also bought a couple of CDs recently by the Claudia Quintet - Semi-Formal and For - which both light up as being HDCD on my Rotel CDP, but aren't indicated anywhere in the packaging. Both are highly recommended!

The Grateful Dead reissued American Beauty and Workingman's Dead on HDCD and they sounded amazing.
