Barry Johnson[1] (born on November 3, 1953), known professionally as Helios Creed, is an American guitarist, singer and bandleader.

He first came to prominence in the mid-1970s with the San Francisco band Chrome, who were considered an early influence on industrial rock.

He plays extra guitar on the song "Gentle Collapse" on the Fist Sized Chunks album by Skin Yard.

[13] His latest album, 2011's Galactic Octopi, was produced by Michael Sheppard of the Transparency record label.

The Dark Matter albums are more electronic and ambient (space music) than his guitar solo work, and performed by old musician acquaintances of his Hilary (bass) and John Stench (drums).
