King Cobain
Grunge Head
Aftermath or Flowers!
There are quite a few to pick from, and also that are all excellent albums. I'll go with "Let It Bleed" with many great songs, "Midnight Rambler" "Monkey Man" and "You Can't Always Get What You Want". "Monkey Man" continues to be a long time favorite song from that album, also the last with Brian Jones, too.
I could be wrong, but I don't think that Let It Bleed can really be considered a Stones album with Brian Jones. I think he only played a little bit on like 1 or 2 tracks and had pretty much been completely replaced by that point. (but I could be wrong).
But since it's in the poll, Let It Bleed gets my vote.
"Let It Bleed" is not really a good pick for an album with Brian Jones' participation though. He had minor parts in just two of the tracks from "Let It Bleed".
Here would be my picks in order of preference:
Flowers
December's Children
Rolling Stones Now
Beggars' Banquet
Their Satanic Majesties Request
Between the Buttons(U.S.)
Out of Our Heads
Aftermath(U.S.)
England's Newest Hitmakers
