Two major music events are going on downtown Des Moines. The 80-35 music festival featuring forty four bands including Broken Social Scene, Matisyahu, Ben Harper, and Public Enemy starts tomorrow night. Today I visited the site of the concert while they set up one of the three stages. I also found out from 80-35’s Jill Haverkamp Matisyahu’s crew wants Olde Main’s pale ale beer to drink during their time in Des Moines. A dozen blocks to the east Des Moines Symphony’s annual Yankee Doodle Pops concert takes on the state capitol grounds tonight. I spoke with the symphony’s conductor Joesph Giunta and Brad Little a Broadway singer who is tonight’s guest performer.
