I’m a Floyd fan... before and after Dark Side of the Moon. Not hard core, but a fan.
The interesting about 1972’s “Dark Side of the Moon” is that it was completely beyond anything that came before or could have been anticipates. It was still in the Billboard 100 for at least into the early 2000’s. It was remarkably genre bending music that appealed to all generations. It was the first thematic LP which demanded listening straight through... in order. It had tons of Easter Eggs, several of which required playing the record backwards. It blended traditional instruments of many types played by virtuosos with nature, Musique Concreté such as running footsteps, machinery noise, screaming and/or muttering, acapello moving vowels and more... all with obvious attention to every second across the entire LP. Most of all, I was personally stunned that this recording reached everyone from young children to the elderly, different languages, etc.
I saw them being handed out free (now on CD) at Software Development 1996 in the Moscone Convention Center. Everybody wanted one. it certainly hit me. Although I had always recognized the greatness of this recording, it was 24 years old after all...
