Gee I don't think I ever heard Charlie Christian playing acoustic. The album I had was called Solo Flight and was all Charlie playing electric guitar. Are there recordings of him playing acoustic guitar ? I'd like to hear them if there are. I really loved Django Reinhardt's acoustic gypsy jazz and though obviously I never got to see him perform I did see Stephane Grappelli in the early 80s playing with some young guitar players who were very Django infuenced in their style .... but as they were touring with Stephane that is not so surprising.
