I was wondering if Lenny would be mentioned.Not as popular as the rock stars.He could play walking bass lines,Comp chords and play the melody all at the same time.Chet Atkiens call him the greatest of all time.His improvisation was the most incredible thing Ive ever heard.He would walk on stage, not having a clue what he was going to play.I dont agree with picking THE BEST of all time so many greats contributed in there own way. But if you had to pick one guy Lenny would be that guy
