So who made the best contribution to the Rolling Stones out of that 2nd guitar slot?
Brian Jones helped push the band to experiment some with different instruments, Mick Taylor was a really good guitar player who was more of a Rock guy than was Jones, and Ron Wood, despite his resume, has basically been a placekeeper in the band.
At least those are some common impressions.
So who, in your opinion, made the greatest contribution to the Stones out of those three? (What line-up was the strongest?)
The Stones peaked with Mick Taylor. The years 1969-1973 was the era of the "Greatest Rock n Roll band in the World"...and they were. It was arguably Mick Taylor's playing that took them to those heights. They did long jams live then with soaring leads by Taylor. Then the stages got bigger, and Jagger ran around, they got a very mediocre lead player (Wood) and they may as well have become figures in a wax museum. I love the Stones, but it was over in 1973. That's not to say I don't love the Jones era, but he was not a special player, Richards dominated then.
