Last night (Oct. 23), Democratic presidential candidate Bernie Sanders held his "Rockin' the Bern" event in Davenport, Iowa and it featured a wealth of musicians, including Alice in Chains frontman William DuVall. The singer performed covers of Tom Petty's "Won't Back Down" and Bruce Springsteen's "Born in the U.S.A." Also featured on stage were musicians Wayne Kramer, singer-songwriters Marshall Crenshaw and Jill Sobule, locals Brother Trucker and Matthew Grimm, punk icon Walter Schreifels of Quicksand, Lisa Kekaula and Bob Vennum of the Bellrays, Sean Kelly of the Samples, Ryan Miller of Guster, Eric Gardner of Street Sweeper Social Club and Brad Jones, according to The Bern Report.

Commenting on Sanders before singing "Won't Back Down," the singer stated, "For quite awhile now, I've had to listen to a lot of mean-spirited talk from people who do not agree with us, saying they want their country back. But, of course, by 'back,' they mean 'backwards.' The thing is, I don't wanna go backwards. 'Cause that's one of the reasons why I'm here tonight — 'cause I'm 'feeling the Bern' and I wanna take it forwards."

The singer performs the Tom Petty cover alone with an electric guitar after some technical difficulties with the acoustic and is joined on stage by several musicians for the Bruce Springsteen cover. Footage of DuVall's performance can be seen below courtesy of Bernie 2016 TV.

Alice in Chains embarked on a month-long tour over the summer, still supporting 2013's The Devil Put Dinosaurs Here. The tour was a special one for the band. Before kicking things off, the band announced, “Thanks to the great people at WMRQ in Hartford, Conn., we became close with a young man named Stefan Dayne-Ankle, who sadly last week lost a courageous battle with Leukemia. To honor Stefan and help give him the memorial he deserves, we’re donating $2 from every ticket pre-sold on this tour.

The album shifted 62,000 copies in the U.S. in its first week, landing at No. 2 on the Billboard 200.
