The recent CD issue of ATMP was remixed at George's request, to tone down the WALL OF SOUND (which I love).
I got a copy on Japanese Red Wax Vinyl, unremixed, around early 80's is its age I think, as a download, in FLAC. I must admit that its MUCH better to my ears. On the remix, its like they pulled all the fader's down or gated the reverb out. But on the unremixed, its lots warmer and fuller, deeper, more mysterious or mystical.
I don't know about Phil Spector personally, but his method sounds great to me, just ask Brian Wilson. I would like folks to judge for themselves though, as we have the "Get Back" bootleg and "Let It Be...Naked" to judge the sound with, many people may not hear the original sound on ATMP. This was an Un EQ'd drop needle FLAC
as close to it can get mix. I much prefer this JRWV version than the remaster, I don't even wanna listen to it, the remaster sounds like they soaked it in digital soap, I'll take the murky analogue any day. The album covers do a great job of illustrating this, bright wishywashy watercolour on remaster, or stark dark mysterious black and white on the original mix.
