Sean William Calhoun | Composer and pianist

Obsidian was written for saxophonist Taylor Scott Brooks. The first movement, Chaos Legion, is groovy, and its title is a reference to the fanfiction Harry Potter and the Methods of Rationality, by Eliezer Yudkowsky. The second movement is titled Double Canon, because it is one (saxes at three measures, at the minor sixth; marimba and piano at one measure, at the unison). The third movement, Purification Swing is somewhat influenced by electro-swing and brasshouse, and is titled in reference to the game OFF.
