I catch Filter in Des Moines doing their soundcheck at a small club. After tearing through a few songs, they spend nearly an hour meeting with fans as part of a radio station meet-and-greet.

'Anthems' was a harsh indictment of American foreign policy; the video for the first single featured an American flag engulfed in a pool of oil, imagery which might have been risque in 2002, but seemed unimaginably passe in the last year of Bush's presidency.

When Patrick finally broke his silence with 2008's 'Anthems For the Damned' - the first Filter album that he recorded sober - fans were decidedly lukewarm.
