Matt & Kim are totally going to do the dance party up right at tonight's show, guaranteed, but let us not forget how awesome openers 31Knots are. Hailing from Portland, 31Knots play a postrock rock with some proggy and arty inflections. My fingers are crossed that they'll play "Chain Reaction," which is my favorite of their songs. I wanna hear singer Joe Haege scream, "MY CAUSE! MY CAUSE! IS DIFFERENT THAN YOURS! RESULTS! RESULTS! SPEAK LOUDER THAN WORDS!" (Vera Project at Seattle Center, 956-VERA. 7:30 pm, $9, all ages.)
