So you're in the mood for some slot machines, some blackjack, some music, and maybe getting an autograph from Mastodon? Good. Mastodon will be signing autographs this weekend at Vegoose Festival in Las Vegas. At 5pm, and only for 1/2 hour, you can catch us at the Zia booth signing copies of Blood Mountain. If you don't already have a copy, what the hell are you waiting for?
