Sunburst is a collection of five tracks recorded and released by Loop between 1988 and 1989, all as part of 12-inch vinyl editions. Sunburst reveals Loop as one of the only UK bands who matched the guitar-heavy onslaughts of American underground rock from the same period, with a neo-psychedelic approach predicated on massed repetitive riffs, drone and distortion. Loop were also not afraid of experimentation, as evidenced by the fractured “Circle Grave” and the 10-minute “Sunburst” itself, which builds into a massive orgy of sound.
