Blogger A. C. Douglas not only took exception to the piece itself, but also to Alex posting it as music. I can think of no non-subjective (or extremely prescriptive) definition of music that Mr. Regucera's composition fails to meet, and Mr. Douglas offers no support for his assertion that that it is not in fact music.
As to the piece itself, It's got some very good stuff in it, especially in terms of texture. It may be a little long for what Mr. Regucera wants to say, but that's a quibble, and hardly definitional.
At any rate, a tip of the hat to Mr. Ross for posting the piece and to Mr. Douglas, for making it essential listening.
