ambient/ noise and related genres in 5.1 DVD-A & BD-A?

Dear Group,
I'm looking for suggestions re: ambient/ noise and related genres in 5.1 DVD-A & BD-A
Its one of those things that's hard to seek out on discogs unless you already know whats out there

I Have
The Grid/Fripp - Leviathon
KK Null - Cryptozoon
Lou Reed - Metal Machine Music

You can start here and filter further: https://www.discogs.sitioby.com/search/?format_exact=Blu-ray+Audio
I have Pierre Henry • Michel Colombier - Les Jerks Électroniques De La Messe Pour Le Temps Présent Et Musiques Concrètes De Pierre Henry Pour Maurice Béjart but not sure if that fits your parameters.

Autechre & The Hafler Trio - ah³eo & ha³oe (ae3o3)

NON · Children Of The Black Sun · CD + DVD
Andy Ortmann · Octagonist · DVD *

* 7.1, but might be along the lines of what you're looking for.

Thanks guys

The Andy Ortmann disc is excellent
I'll work through the other suggestions
