I have just made one of my occasional checks of YouTube to see if the complete Rolling Stones in Mono playlist is still there, and yes it is. The Rolling Stones have 2.5 million subscribers on YouTube, but I am one of only three subscribers to the mono collection. This is crazy! It isn’t a playlist that some fan threw together, it’s official. I bought the set for $110 as a collection of 96 kHz/24-bit FLAC files. In MP3 quality it will cost you a hundred bucks, and the CD set goes for over $200. But here it is, complete for free.
The attention paid to curating and mastering this set in original, true mono was unprecedented. Read all about it here: https://theaudiophileman.com/stones-mono/
