Born in 1955, Sergei Shutov was an artist who used painting, drawing, sculpture, photography, and A/V installations to react to and comment on the restrictive cultural atmosphere of his native Russia. Shutov corresponded with Brian Eno and told him that it was hard to purchase Eno recordings under the Communist regime. Eno’s solution was to personally compile this album as a gift for his friend. The Shutov Assembly consists of unreleased tracks that Eno had contributed to various sound installations and art festivals over the course of the '80s. The album falls into the tradition of Eno’s “Ambient Works” series, though this music is far more ominous than the recordings he'd made in the late '70s and early '80s. Where there was a kind of sweetness—even humor—in Apollo: Atmospheres and Soundtrack, these tracks feel like the accompaniment to potentially more hostile environments. Not that that makes them any less hypnotizing. No matter which song you choose as your entry point, this is music that will slowly suck you into an altered state, soothing even as it unnerves.
