On The Clap - here is the note on that track from the 2014 blu-ray set, top of Page 7 in the booklet. Quote: "The live version of 'Clap', as it appeared on the original album, was upmixed to 5.1 using the Penteo Surround system, as no multi-channel recording exists for that track."
So this 'fake surround' Clap is also the 5.1 version that appears on the new 2023 box set blu-ray. I don't hear any adjustments between the 2014 and 2023 versions of Clap on the 5.1s on the two blu-rays. As noted in the poll thread, I like both versions - the atmos and the 5.1 of Clap. In isolation, the atmos feels truer to the single instrument live concert 'reality' - but it does sorta interrupt the atmos flow, being bookended by those two wonderful atmos behemoths, YIND and ST. While the Penteo 5.1 upmix, sorta keeps the surround flow, well, flowing! All good, right?
