Eighty-three-year-old psychoacoustic innovator Alvin Lucier’s Criss-Cross, performed by doom-metal guitar spelunkers Stephen O’Malley and Oren Ambarchi, is the centerpiece of the three-day Tectonics Festival. This unique occurrence, curated by Icelandic Symphony Orchestra music director Ilan Volkov, is debuting in the U.S., and without a symphony at its disposal; instead, the festival focuses on works for soloists, duets, and other small configurations. Tonight’s program offers works by younger composers including Eyvind Kang and Iancu Dumitrescu, alongside pieces by venerable avant-gardists Lucier and Italy’s Giacinto Scelsi. On Saturday, the late composer Harley Gaber, who committed suicide in 2011, is remembered with a rare performance of his 100-minute minimalist monument The Winds Rise in the North. Tectonics wraps up Sunday with a solo set by cellist Hildur Ingveldardottir Gudnadottir.
