Indie rock icon Bob Mould (Hüsker Dü, Sugar) discusses his creative journey -- a childhood obsessing over jukebox 45s he got from his dad, his experiences in the Minneapolis/St. Paul punk scene, his current life in Berlin -- and how those touchstones inform his excellent new album, Sunshine Rock. Also featured: an excerpt of a backstage interview with gospel and R&B legend Mavis Staples at Lollapalooza 2010.
