These are recordings from two improvised sessions at The Tank Center for Sonic Arts in Rangely, Colorado; a water tank from 1940 in the rural West that has been converted into a performance space with an exceptionally long reverb time. The first session in 2018 features Nicholas Miller, Bridget Hartman, and Alma Engebretson. The second session in 2022 features Nicholas Miller, Bridget Hartman, and Camille Backman.
