I have a short list of really really amazing rock guitarists I want to see perform live, some of whom I have already seen, and some yet to come. Here's the current list (as much as I can remember at the moment) in no particular order.
Eric Clapton (seen)
Jeff Beck (seen)
Jerry Garcia (seen several times)
Carlos Santana (seeing him 24 March 2011!!)
Mark Knopfler (yet to be scheduled)
Jorma Kaukonen (yet to be scheduled)
