Complete Musician? I don't think such a musician exists for, in every art form, painting, drawing, writing, etc., completeness can't be reached for there's just too much to learn and new material, techniques and innovators keep emerging and evolving. Isn't it that incompleteness that keeps us going and wanting for more? I doubt that the above mentioned musicians and composers would call or would've called themselves complete. Their inner drive for more and better creations is proof.
