Barry Johnson, 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. Chrome broke up in the mid-1980s when founding member Damon Edge moved to Paris. Helios then recruited some local hard rock musicians and launched a solo career.

Chrome is an American rock band founded in San Francisco in 1976 by musician Damon Edge and associated with the 1970s post-punk movement. The group's raw sound blended elements of punk, psychedelia, and early industrial music, incorporating science-fiction themes, tape experimentation, distorted acid rock guitar, and electronic noise. They have been cited as forerunners of the 1980s industrial music boom.
