American composer John Adams and I first met in the late 1970s, when I became one of his composition students at the San Francisco Conservatory of Music. My recollections from those days endure as near-cinematic images: John lugging his homemade synthesizer—he called it "the Studebaker"—down the hall prior to meeting me at his office; an early performance, at Mills College in Oakland, of Adams's Shaker Loops (footnote 1) for string septet; sitting with Adams during rehearsals for the 1981 premiere of his choral symphony Harmonium (footnote 2), with Edo De Waart and the San Francisco Symphony.

As I wrote before in these pages, I have long been acquainted with French electronics manufacturer Trinnov. Years ago, at an Audio Engineering Society convention in New York, a Trinnov rep used a mastering console equipped with their processor to move, at will, the sounds of instruments around the 3D soundstage and left me thoroughly impressed. That was before my conversion from stereo to multichannel music listening, and before the blurring of borders between home theater and mainstream audio.

What’s the most frequently performed new opera in America at present? It’s Laura Kaminsky’s 2014 chamber opera, As One, whose libretto by Mark Campbell and Kimberly Reed explores the coming out process of its protagonist, Hannah, as a transgender woman.
