This is what the composer says to this music:
"I was listening a lot to the music of Giacinto Scelsi at the time when I wrote this piece. I remember sitting an evening listening to some trombone pieces. I felt deeply that I wanted to write something similar, but didn´t feel comfortable copying his ideas.
I went to bed and woke up in the middle of the night certain that Scelsis ghost was standing at the foot of my bed telling me that it was ok to write a similar piece. The next morning I got out of bed and wrote this piece in 2 hours."
