As a teen I was a big Stones fan. In 1979 their tour came through Chicago. I told my best bud " We gotta see the Stones. Their all mid 30's now and this will probably be their last tour". Boy was I wrong, lol. 35 was old to a 16 year old.
I have alot of their albums. Most are not great quality. Exile probably worst. Appearently it was recorded on some moble gear. Probably too much dr*gs and alc*hol for them and crew to care about quality.
Undercover is surpriseingly good on vinyl. Very clear, dynamic and that machine gun guitar riff is goes way beyond speakers.
