The first (and only) time I saw Mastodon was at the Pitchfork Music Fest in 2007. I knew who they were and I'd heard a couple of songs, but I was completely unprepared for the amount of rock that they unleashed. It was one of the highlights of my weekend, way better than Yoko Ono's light show that night. They're heavy metal the way it should be; loud and fast.
If you haven't heard of them yet, you should pick up their newest album, Crack the Skye (you can listen to it here, too). If you have heard of them, then you're probably one of the people that can't get in to their sold-out show this Thursday night (4/30) at the Metro. Lucky for you, we can help. Thanks to the tour's sponsors, ShockHound.com, we have two pairs of tickets to give away. E-mail us at email@example.com with the subject line "Mastodon" to enter. We'll pick two lucky winners on Tuesday morning! It's as simple as that. I assure you, you want to see this show. If you can't make it to the show in Chicago, perhaps you can find another date on their schedule that suits you. Good luck!
