A form of headbanging adapted for the sludge metal genre of music. It is a full body motion often performed with bent knees that involves an initial leaning-back followed by a vigorous lunging-forward motion in which the sludgebanger's head can come dangerously close to hitting the ground. Pro sludgebangers are known to be capable of bringing their foreheads to within 10 - 20 nanometers of the ground without contact.
Band members of the popular sludge metal band ISIS can be seen sludgebanging during live performances.
