Hi, just a comment to this. When listening carefully to Little Walter you hear a lot of pulls and slaps. And how he accompanies himself between the phrases. Also on Juke, a lot. A style I think he had cause played so much alone before with a band. In the opening of Too Late this can be easily heard. Goes between the main playing to accompanies in the low register. Without the slaps, pulls, tongue blocking and that kind of accompanies impossible to catch Little Walter sound. If needed or wanted. The "melodies" are easy to learn. These things really hard. That is why "nobody" sounds like Walter. Cotton played and plays a lot of Walters riffs etc. but without this Walter style. James has his own unik sound although playing a lot of Walters phrases. So in this way worth trying to play everything like Walter in Juke and other of his songs to learn those things that can be useful sometimes even if you want to be yourself with your own sound. This is how I feel.
