I’ve been playing music professionally for decades and have also spent many years as an overpaid live sound system designer and mixer.
Thank so much for joining this thread. Must be a fun way to make a living! The link in my OP was specifically about live performances at Vegas residencies.

Kind of Blue in Atmos is available on Tidal and Atmos music, highly recommended, see "Stunningly Good in Atmos" below:
