In 1984 Steve Roach released what remains one of his two best known recordings, Structures from Silence. Now, nearly 40 years later he returns to that sound on the album, Rest of Life. It’s a double CD of mostly quiet and deep ruminations. There’s no digeridoos or modular synthesizers, but there is the electric violin of his wife, Linda Kohanov. From their home in the Arizona desert, they talk about revisiting the spirit of Roach’s Structures from Silence, and horses.
