This week I'm giving away The Best Seats on the Rocks for Wilco's August 10th concert at Red Rocks. Sleater-Kinney will open the show. Jeff Tweedy made cameo appearances twice on the TV series "Portlandia," which starred Sleater-Kinney's Carrie Brownstein, and Fred Armisen. Here's a clip from 2014 where Jeff is in the recording studio getting songwriting advice from record execs played by Carrie and Fred. (photo: Getty Images).
