While details surrounding the incident were unclear at press time, Mastodon guitarist Brent Hinds suffered what has been described as a "severe" head injury in an incident that took place sometime after the VMAs early Monday morning. He remains under physicians' care in a Las Vegas hospital.

Hinds' nose was also broken, and he sustained two black eyes, according to the band's manager, Nick John. Although John did not provide details about what led to Hinds' injuries, he said they occurred at around 3 a.m. Monday morning, after the band had finished one of the highest-profile performances of its career—a guest spot in the Foo Fighters' suite during Sunday's MTV Video Music Awards at the Palms Casino Resort in Las Vegas. Mastodon performed their single "Colony of Birchmen" with Queens of the Stone Age frontman Josh Homme; the song appears on the band's 2006 LP, Blood Mountain.

Witnesses to the incident at a Las Vegas hotel claim Hinds was attacked. A spokesperson for Warner Brothers Records had no comment other than to say that the guitarist was expected to make “a full recovery.” --Joe Bosso
