One album that struck me as very analog is Fleetwood Mac s\t. Now, I am not hugely familiar with everything they've done, but I snagged this from a friend who was selling some CDs. Anyway, this one is so big and fat sounding it doesn't seem like it matters what format it is, it just sounds freaking good.
To me it's totally the recording format. The way the music was recorded. That's the whole deal right there. Those big 2" 24-track recorders they have in the studios are amazing. I have an ADAT and do all my multi-tracking with that, but man, I bought a used cassette deck (defective, even!) and when I laid down some drums on that thing I thought, "Wow, I forgot how good analog tape sounds!" Sure, there's problems with it. The hiss, the speed problems, dropouts etc. But the gentle compression is just so cool and forgiving. I wish I had the ability to maintain an analog multi-track properly, as it would probably work wonders. With digital I was initally impressed at how identical the input and playback sounded. But analog comes back sounding better. Technically worse, but better somehow!
To me the ADD or AAD-tagged discs always were superior to the DDD stuff. It's just a more romantic sound. So much of modern recording technology is an attempt to mimic old recording technology. It's really kind of ass-backwards if you think about it.
