Before becoming A-list pop stars due to factors musical (gussying up their sound with soulful flourishes and studio panache) and nonmusical (bassist/mouthpiece Pete Wentz marrying and divorcing Ashlee Simpson), Fall Out Boy was ostensibly a punk band. But since crossing over with 2005’s “Sugar, We’re Goin’ Down” and maybe even before that, they’ve never released a song that so wholly embraces the canonical ideal of punk rock as much as “Love, Sex, Death,” the one minute and 24 seconds of knuckle-dragging hardcore bombast they kicked out today. And which producer coaxed all this aggression out of them? None other than noted punk/metal enthusiast Ryan Adams, who’s been indulging his own punk proclivities lately. Fall Out Boy spent two days recording at Adams’ Pax Am Studios in Los Angeles to make Pax Am Days, a new album to be released digitally and as the second half of a duo disc reissue of this year’s other Fall Out Boy LP, Save Rock And Roll. If “Love, Sex, Death” is indicative of the rest of the set, Pax Am Days will be quite the contrast to Save Rock And Roll’s hyper-glossy emo jock jams. Hear the new song below.

There’s a tour footage video for it too at Rolling Stone.

Pax Am Days is out 10/15 via Island. Pre-order it here.
