At last Saturday's NFC Divisional playoff game, legendary Seattle rockers Jerry Cantrell and Sean Kinney of Alice In Chains, along with Seattle native Duff McKagan of Guns-'N-Roses fame, snapped a "selfie" and posted it on Instagram.

It is no secret that Cantrell has been a fan of the Seahawks since their inception in 1976. Growing up in Spanaway, WA, the driving force of AIC has raised the 12th Man flag before a Hawks game and even attended Super Bowl 40 when Seattle was beaten by Pittsburgh.

Cantrell and his band mates will get to add another line to their Seahawks resume this Sunday when the perform at halftime of the NFC championship game at Century Link Field, as it was announced on the band's Facebook page.

With that, here is a primer for the upcoming game and entertainment. This video, entitled "I'm In Again" is a tribute to the fans and uses the Alice classic tune "Would?"
