 Formed in the North East of England in the late 1970s, Hollow Ground became one of the cutting edge groups of the NWOBHM period.Although they only released six tracks, these have come to be considered a classic example of the style of the era.In 1980 they released the "Warlord" EP, containing the tracks "Flying high," "Warlord," "Rock on", and "Don't chase the dragon."
