I came here because I read this on a website "Django Reinhardt’s Improvisation No. 1 is considered by many to be one of the greatest solo guitar works of all time." I was robbed - this is nothing more than finger exercises. Last time I trust the internet to inform and educate
Charles Delaunay (in his book on Django) describes how one of these improvisations came about. Nothing had been planned. Delaunay and Reinhardt were in the record studio; Delaunay just told him to make up something, and Django cut loose out of nothing.
