SSC, you always outdo yourself. Graphic scores now? I love that you are exploring that new space (at least from the few pieces I've been able to see from you). During my Masters program I was pushed to write a lot of this time of stuff, and I always enjoyed it. But take note, it is not easy to do right.
I like the "In C" type ideas in the pulse sections, and the faster passages that you get from those (at points) really help to break up the monotony of the sustained slower portions of the work.
Pulso 3 is interesting, especially having that "libre" part. I'm curious as to how you coached the players on how to interpret the passages.
In any case, great job, I rarely get to see pieces like this in this forum. So a breath of fresh air.
