This is a standard Jazz Blues with added 'Coltrane' substitutions that make a really hip sounding line with dominant descending thirds over the first four bars. I've moved the traditional changes up to the alternate chord area so you can still have them for reference. From a No Treble post by Joe Hubbard, all rights and credit go to him.
