Jazz
Duke Ellington: Piano In The Foreground * (Columbia/Legacy CK 87042)

While remastering this disc, it looks like the engineer used the Pacific Microsonics AD Converter (evidenced by the HDCD indicator showing up) on a number of tracks, but not all of them. No PE or LLE applied on the HDCD tracks, but the Transient Filter indicator flickers YES very often. Still, it's a great disc!
