Fall Out Boy, the hometown heroes of Chicago’s adolescents, is back with a new single.

The single is the band’s first new music since 2009.

“My Songs Know What You Did In The Dark (Light Em Up)” was released Monday. It was accompanied by news of a new album–Fall Out Boy’s first since 2008–as well as a tour.

In 2009, Fall Out Boy announced an “indefinite hiatus,” setting off years of confusion regarding the band’s status. Each member worked on their own side projects, including singer Patrick Stump’s 2011 solo album, Soul Punk and bassist Pete Wentz’s electropop band Black Cards.

As ostentatious as ever, Fall Out Boy is titling its fifth full-length album “Save Rock and Roll.”

“When we were kids, the only thing that got us through most days was music,” the band said through its website, FallOutBoyRock.com. “It’s why we started Fall Out Boy in the first place. This isn’t a reunion because we never broke up. We needed to plug back in and make some music that matters to us. The future of Fall Out Boy starts now. Save rock and roll….”

In the 10 years since Fall Out Boy’s first album release, the band has achieved a special kind of notoriety. Wentz’s oft nonsensical lyrics were hard to take seriously despite Stump’s blistering vocals and some seriously catchy music.

Combined bratty onstage antics and Wentz’s high-profile marriage and divorce to Ashlee Simpson made Fall Out Boy a popular whipping boy by critics.

However, Fall Out Boy has never been too concerned with the critics. Its lyrics and music videos frequently poked fun at the well-oiled entertainment machine. The band also shirked its original pop-punk aesthetic in order to move with trends, employing dance-hall beats, plenty of autotune and guest performances from Lil Wayne and Jay-Z.

Following the recent trend of reunion tours, Fall Out Boy announced a string of tour dates to accompany its new album. The tour kicks off May 14 at the Riviera Theatre, 4746 N. Racine Ave. in Chicago.

Whether or not rock and roll actually needs saving is beyond the point–the 33-date tour reveals that, in classic Fall Out Boy style, the band is just going to do it anyways.

“My Songs Know What You Did In The Dark (Light Em Up)” is available on iTunes. Save Rock and Roll will be released May 7.
