It’s been a while since we’ve heard some new stuff from Desaparecidos, the punk band spearheaded by Bright Eyes’ Conor Oberst (the last full-length was 2002′s Read Music/Speak Spanish, the last single from 2003), but two, brand new tracks made their way to the public today, and sport some pretty heavy messages.

Among this news is also a confirmation that the original band is, in fact, reuniting for a tour, kicking off with a performance at Omaha’s MAHA Fest.

But first, let’s dig into one of the tracks, “MariKKKopa.” With a name like that, there’s sure to be some strong emotion attached.

Oberst recently talked with Huffington Post about the inspiration behind “MariKKKopa,” as well as giving it such a shocking name.

Arizona SB 1070, the 2010 legislative act in the state of Arizona, is Oberst’s driving force in the new track, which he has said holds great importance to him.

The act required all immigrants into the state to carry citizenship papers on them at all times, and garnered the most controversy over the “random searches” by sheriffs in the state on anyone who they judged to be immigrants.

“I’ll never understand how destroying families through deportation benefits our society,” he tells Huffington Post.  ”How we treat the undocumented says a great deal about us as a people and whether or not we’ll continue to fulfill the fundamental American promise of equality and opportunity for all.”

Oberst takes his main stabs at sheriff Joe Arpaio of Maricopa County, who many have deemed “the toughest sheriff in the nation” because of his involvement in SB 1070.

In an interview played at the end of “MariKKKopa,” Arpaio is heard talking about how he had been compared to the Ku Klux Klan, saying that it was an “honor” because it meant he was “doing something.”

Going off of this at the start, Oberst said he decided to create the track in the view of these sheriffs and their supporters, in order to convey “the unbelievable level of vitriol and hatred that comes from some supporters of these anti-immigrant laws.”

Listening to the track itself, hearing lines such as ”it’s their turn for someone to get hurt,” it’s easy to see how strongly Oberst and the band feel about the issue.
