I think I'll find that there was a guy named Brian Jones prior to Mick Taylor and when he began losing interest in being purely a guitarist, as well as having substance abuse issues, Richards took on all guitar until Mick Taylor was hired. Jones played guitar in two songs on Beggars Banquet. On Let it Bleed, Jones played no guitar and Taylor played in 2 songs. You can hear Richards' and Taylor's contrasting styles in Sympathy for the Devil on Get yer Ya-Yas Out since Richards plays the first solo and Taylor the second. My preference is for Richards' style over Taylor every time.I think that you will find that it was generally either Mick Taylor or Ronnie Wood that did the solos for the Stones. Richards is basically a rhythm guitarist.
