Figure this place would be a good place to post this. Last time I went and saw Amon Amarth I headbanged so much I could barely move my neck for 3 days (not kidding), and that was a 45 minute show! With them coming back, I have to ask...how they hell do the windmill so fucking much without breaking their necks?? Is there a trick to this type of headbang? I've got 90 minutes to snap my fucking head off in less 2 weeks. Any advice would be helpful .
