"Alice in Chains w/ Northwest Symphony Orchestra," by Seattlest Flickr contributor architecturegeek

In the midst of Seattlest's angst over the Seahawks' 33-30 overtime loss last Sunday to the Niners, we totally forgot to mention that Alice in Chains played at halftime. Duh. The 12-minute performance featured Led Zeppelin's "Kashmir," and the band was accompanied by the Northwest Symphony Orchestra and some righteous smoke machines. Aside from the music, our favorite moment in the set was when Niner long-snapper Brian Jennings came onto the field to warm up, but instead made beeline for the stage, where he grooved out until the music stopped. Dancing alone in front of 67,000 people? Well done, Brian.

AIC is rumored to be heading to the studio next month to produce the band's first album in over a decade. The band is holding a fantasy football contest on their website. They love their football, apparently.

Crappy video alert (after the jump)!
