Roger McGuinn in my opinion is such an underrated guitarist. His Rickenbacker play on many of the Byrds songs was out of this world, but Eight Miles High his work was amazing on guitar. Later on in the group they added another fantastic guitarist in the late Clarence White. The Byrds also had another underrated songwriter in the band in the early days in the late Gene Clark. With added harmonies from the great David Crosby early on this band was fantastic.
