G. F. Haas, I can't breathe

Marco Blaauw, the brilliant trumpeter of Musikfabrik, plays Georg Friedrich Haas's I can't breathe (In memoriam Eric Garner). Haas writes: "[The piece] begins quite traditionally with a dirge: a free cantilena in twelve-tone space. Then the intervals constrict; the song becomes more and more smothered, ultimately in a 16-note scale. The dirge constricts within a sonic space of other trumpet notes of extreme registers and changing colours — cautionary symbols, perhaps, of the world from which the victim was violently torn away. I give no notes to the perpetrators." (Via Emre Tetik.)
