If commitment is the measure, then Max Richter’s deservedly well-received *Sleep*, his eight-hour sonic paean to slumber, has one major peer this year. That would be Taylor Deupree’s ongoing [2015 Studio Diary](https://soundcloud.com/12k/sets/taylor-deupree-2015-studio). At about 70 tracks so far, the diary is only half the length — just under four hours — of Richter’s *Sleep*, but like Richter’s work, Deupree’s balances length with lightness, intensity with a soft touch. The October 12 entry, “a piano in autumn,” is little more than a digital piano refracted over the course of a minute and a half, as minor artifacts of tone are extended and warped while the full, simple piece continues. It’s Satie on pause, Feldman heard from a right angle. It’s a work composed entirely of grace notes.
