The Dog Star Orchestra not only presents some of the most interesting chamber-music experiments in the city, the collective tends to stage them in unusual locations. On Friday at Automata, Dog Star hosts a concert of “text and graphic scores that directly engage with nature and natural environments” with works by such composers as Christian Wolff, Katherine Koopman, Heather Lockie and Jack Langdon. On Saturday, vocalists lurk in the pedestrian tunnel at Southwest Museum to intone new pieces for voice and objects by Lockie (with choreography by Jordan Saenz), Carolyn Chen and Laura Steenberge. Performers include Saenz, Ariana Daub, Amir Rappaport, Nicole Nistal, Argenta Walthers, Jess Basta, Tany Ling, Marja Liisa Kay, Linnea Sablosky, Stuart Wheeler and Jessica Hemingway. An earlier subterranean piece by Lockie, Song to Be Performed in a Tunnel in Your Town, was a mesmerizing weave of vocal exhalations that resonated eerily through time and space at a 2018 Dog Star performance.
