as far as favorite Jazz album to show off the system; wow, there are so many.......I like Chick Corea too, but Ellington's 'Jazz Party' and Ben Webster's 'Live at the Renaissance' are more where my vision of that would be. both from the musical flow and chops, and recording quality, I think that those might set the bar pretty high. then there is Armstrong and Ellington, Together Again for the First Time. 'Duke's Place' is a force of nature. Wow! or maybe almost anything with Count Basie. you cannot go wrong with any Basie 'Pablo' as a demo disc. Miles Davis 'Live at the Blackhawk' is fantastic.....the master at his peak. I have a 15ips 1/4" of that that I love.
if you play any of those records, and then play JATPS.....well.....it's not really fair at all. those 70's Swedish guys are pretty good, but they are not in that league. OTOH, if you play JATPS unto itself as it's own thing then I think it works for me. it is a great recording, it's energetic, it's rousing and flows and builds nicely. but it does get repetitive and it's a bit hokey but mostly I like it if I don't play it too often. maybe it's better as a demo disc than a sit back and enjoy type music.
if I play JATPS for visitors they do like the sound, but when Webster's tenor opens 'Georgia on my Mind' at full tilt boggie the listeners are gobsmacked big time. many orders of magnitude difference.
