The track “welcome to the machine” is equally awesome, with the pulsing sounds of the machine chugging away in each of the four corner speakers in turn.  By https://www.versedautomation.com/ 

The second is a surround sound DVD of Depeche Mode’s “Violater” album. Someone has really spent a lot of time listening to the tapes and deciding which instruments and effects should go where in the soundscape. If you know the album as i thought I did, hearing it in 5.1 is a revelation in discovering little bits that escaped me when listening in stereo, even on quality headphones.
