I looked at it and thought it looked only slightly cool - there's only so much you can do with that iconic imagery.
When it was released in the Immersion box set in quad/5.1 I bought it an invested in a surround sound system.
That was a pricey business matching a pair of expensive front speakers with rear equivalents (particulary required for quad according to what I read) but I found out not too necessary.
I found out the quad/multi channel mixes added so much to the sound quality and entertainment value that I was blown away!
Wish You Were Here was/is also stellar.
I then obtained the surround mix of Tubular Bells and was again knocked over as it was designed as a 4 channel mix.
What I knew from my youth as a rather duff sound sprang to life - no longer were all those instruments mixed down to two channels but came to life in 4 channels. Wow!
On DSOTM there's a section where someone is running between the two stereo speakers (in a train station or airport?).
In the surround version, he's running in circles round the room.
I managed to source around 200-300 digitised quad albums but mostly obscure.
There's a few more Floyd albums but there's theres also |Fleetwood Mac Rumours - and - the original ELO album which is also unexpectingly stunning.
Unfortunately, I no longer have the space and money to justify two separate systems, but they should be on your bucket list for those albums.
