In advance of the forthcoming comeback album from Fall Out Boy, bassist Pete Wentz has taken to the band’s website to promise a “diverse” cast of guest appearances on Save Rock and Roll (out April 16).

“So I was thinking about some of our past features (ones that stuck with me): Jay-Z, Brendon Urie, John Mayer (guitar), Debbie Harry, Lil Wayne, and Elvis Costello,” Wentz wrote on the band’s site today (March 12). “The features that we have on Save Rock and Roll will be just as diverse – we are fans of all different kinds of music and the features will reflect that. If anything we have gone farther…”

True to Wentz’s word, the music video (below) for the album’s first single, “My Songs Know What You Did in the Dark (Light Em Up)” features hip-hop star 2 Chainz, who also joined the band onstage to add a rap to the song during an appearance at this year’s NBA All-Star Weekend.

Save Rock and Roll will be Fall Out Boy’s fifth studio album, the band’s first since the hiatus implemented following their 2009 release, Folie à Deux.

Wentz recently published his first novel, Gray, a fictional rock star memoir that looks at the darker side of life on the road with an emerging band.

FOB frontman Patrick Stump, meanwhile, published a piece taking down Internet hate culture just last week.
