Headbanging

[9] During a show at the Boston Tea Party concert venue, audience members in the first row were banging their heads against the stage in rhythm with the music.

Specifically during the performance of Sunshine of Your Love, front row audience members with particularly large amounts of hair are seen quickly bobbing their heads to the music in a fashion typically associated with modern headbanging.

[13][14] Lemmy from Motörhead, however, said in an interview on the documentary The Decline of Western Civilization II: The Metal Years, that the term "Headbanger" may have originated in the band's name, as in "Motorheadbanger".

Lewis would continuously flip his hair back away from his face, prompting the fans to mimic the movement in rapid repetition in a fashion resembling headbanging.

[19] In 2007, Irish singer and former Moloko vocalist Róisín Murphy suffered an eye injury during a performance of her song "Primitive" when she headbanged into a chair on stage.

[20] In 2009, Slayer bassist/vocalist Tom Araya began experiencing spinal problems due to his aggressive form of headbanging, and had to undergo anterior cervical discectomy and fusion.
