Here is my first try at JH 5 Grain Levain - with actual levain from my sourdough starter.  My previous versions of this bread were with only commerical active dry yeast.  I was happy with it, except wished for more rise/height in the boule.

I think the seed topping is not part of the original recipe.  I just can't resist the toasted seed flavour the topping ads to these kinds of breads.

Just wish I got the same consistent open holed crumb in my same day's bake of the Tartine Country loaf.
