If you ask me, one of the cooler things about being a Seattle sports fan is that you never know when a grunge star from the '90s might show up to whip your team into a frenzy.
A few years back, I was at Qwest Field for a Bears-Seahawks game when Jerry Cantrell of Alice in Chains and Matt Cameron of Pearl Jam (and Soundgarden) shared 12th Man duties. The PA played snippets of songs from both bands and, as far as pregame scenes go, it was one of the loudest — and most memorable — I've experienced. The place was just going nuts.
Not a bad way to start a ballgame, even if it didn't rub off on Felix Hernandez and the Mariners.
