Thanks, I was able to confirm that the version streaming in Spain is just stereo.
How is the 5.1 in the extra tracks?
I’ll quote myself. The extra tracks “are indeed in surround, though subtle: echoes, a bit of synth, distorted voices and some crowd, of course. It enhances A New Machine, for sure.” On repeat listenings more subtle things are found in the rears, though the mix is front heavy. I had already bought the single blu ray but I’m happy to have these other parts of the concert that were excluded.
