An astrobleme is an eroded remnant of an impact crater, etymologically translating to “star scar.” I first encountered the term driving south on U.S. Highway 385 from Ft. Stockton, Texas towards the town of Marathon. The signs are small and flash by fast: “Entering Sierra Madera Astrobleme,” then only a few miles later “Exiting Sierra Madera Astrobleme.” If you blink and miss them, you wouldn’t even know that you had just casually traversed what remains of a 100-million-year-old impact crater eight miles in diameter. I find peace seeing how Earth’s omnipotent erosive nature heals, even after such a catastrophe. I associate nature with asymmetrical rhythm and erosion with fractals, so the structure of this piece is based on fractals of the theme rhythm heard for the first time (at the two-bar level) in the brief central section of the piece (Letter C). I’m not sure how much a listener might perceive any of these macro-formal elements, but I guess that’s the point. I hope this piece is a little Rubik’s cube for the performer and a bass-y sound bath for the audience.
