Excellent input, thanks! I totally agree — that album is a sconic masterpiece. I suppose it is no coincidence that Alan Parsons was the audio engineer.
The Dark Side of the Moon has spoken to me in different ways throughout my life, which says something about the timeless appeal you cite. I also listen to the album multiple times in a year. I recently purchased the immersion set, which delivers the album in Blu-ray 5.1 sound. If ever there was an album made for a 5.1 remix, it’s Dark Side of the Moon.
Thank you for mentioning other artists who make the studio one of the instruments. Biosphere also comes to mind.
I’ll contribute more articles about album cover art, which is one of my favorite topics.
