Abyss, Life

These past few weeks I've been obsessing over this work. 

It began as an homage to Ligeti and Denisov., which produced this first version.  

But the thing kept buzzing in my mind and so I intercalated new contrasting sections with a faster tempo.

Finally I added some transitional sections. And so this is its first final form.

Edit: added the score

At first I didn't see the relationship well, but after two minutes the orchestral mass effect is more noticeable.
I know Ligeti's work but not Denisov (I will investigate).

I liked your work very much. I think that in addition to that sound mass effect, what is more worked is the multiple timbre lines. It is a very well resolved framework.
