best seed and soil for shade only grass

Looking to finally tackle my backyard grass problem. Half of it is covered by trees and shade to the point where it's even difficult for weeds to grow. Is there a grass seed worth attempting to grow?


You can clearly tell where sunlight reaches through when the trees have their leaves.

I called Clegg's and they recommended I go with river silt instead of top soil. Would also like to know thoughts on this as well.
