James Tenney originally wrote Saxony, an ecstatic extrapolation of the natural harmonic series, for one or more saxophones; he also made a brass-quintet version, which went unplayed until WasteLAnd, one of the country's most far-sighted new-music series, presented it in Los Angeles last spring. The performers were Allen Fogle, Matt Barbier, and Luke Storm, of Trio Kobayashi, plus Aaron Smith and Hopscotch's Jonah Levy. It's great to see WasteLAnd uploading videos of its concerts; I also recommend Ashley Walters's rendition of Liza Lim's Invisibility, from the same 2015 concert, which I was fortunate to attend.
