March 15, 2011, the band released its first album in eleven years, First World Manifesto on Fat Wreck Chords. It was produced by Mike Kennerty of The All-American Rejects. It was announced that the label will also be releasing the back catalogs of Screeching Weasel, the Riverdales, and Ben Weasel. On March 18, 2011, during Screeching Weasel's South by Southwest Festival performance at the Scoot Inn in Austin, Texas, Foster punched a female audience member who had thrown a beer and ice cubes at him, and also spit in his face.
