I listened to the Kenny Burrell again this morning. I'm not an audiophile but it sounds good to me. Perhaps some listeners didn't like being told to "Get Happy".
Not officially announced yet but this is a forthcoming Tone Poet release. Joe Harley mentions it near the end of this podcast https://www.soundsvisualradio.com/podcast/sounds-visual-radio-episode-joe-the-tone-poet-harley/
I was pleasantly surprised by disc 1 as well and listened to it 3 times over the weekend. I regret not buying the Japaneses version as the US releases has below average packaging.
