U2 will release their first full-length album in nine years, "Carnaval De Luz," on November 12, Interscope Records announced Thursday.

The album closes with a duet with Dolly Parton, "Torn," described in a release as "what has sadly turned out to be her last recorded vocal performance." Parton recorded the vocal in June. The song was co-written by U2, Parton and Johnny McDaid and is described as "a tender country song detailing broken family ties that holds wider resonances." Daniel Lanois plays pedal steel on the track.

"When she got ill," Bono told Rolling Stone, "she got out of her bed to sing this song. And you can hear that. And I can't even listen to it now… She sang her heart out, and I cannot believe that's an 80-year-old woman."

Bono explained to Rolling Stone how the collaboration came about. He had asked Parton to participate in an Irish folk-themed side project, but after he played her demos over the phone, "she said, 'That's a little too Irish for me.' But she said, 'I got this song. It's called "Torn," and do you wanna see where you can take it somewhere else, maybe?'" Bono and McDaid then rewrote the lyrics to make the song about a mother watching her family splinter, and, according to the magazine, Parton agreed to sing the new version.

Interscope previewed the album Thursday with a new single, "Silencio," released to streaming platforms alongside the announcement. The release describes the song as a "2mins 35second homage to early surf-punk insolence." Ryan Tedder contributed additional production to the track.

The album's cover shows the band strolling in a line by the seaside. The release characterizes the record as "a collection of 12 songs exploring themes of spirituality, friendship, freedom and endurance in the face of dark, encroaching forces." Longtime collaborator Jacknife Lee produced the set.

Other contributors include Brian Eno, who co-wrote and played synthesizer on "Go (Carnaval De Luz)," "The Greatest Show on Earth" and "Can't Stop Us Now," Martin Garrix, who co-wrote "Glorify," and Lanois on pedal steel for "Torn." Cliqua — the Mexican-American directing duo of Pasqual Gutiérrez and Raúl "RJ" Sanchez — directed the "Silencio" video, shot in Mexico City earlier this year.

"Roll up, roll up, roll up! Bring your purple socks, your broken hearts, your rose-tinted naivety… oh be amazed in the hall of mirrors," Bono said in a statement. "There will be loud guitars, deep bass, some ecstatic rhythms and, yes, some silver tears will make an appearance!… 'Cause in the near distance just outside our carnival of light there are all kinds of creatures… the same imagination that brings us our creativity can also bring us monsters. So we make the drums louder. We build a bigger fire. We make our stories wilder and funnier. We make the melodies sweeter and the songs, they better shine, because if the world is in darkness we better not be."

The Edge kept his assessment shorter: "It's a messy, provocative, sacred collection of songs — and features the first-ever use of flat-wound strings on a U2 recording. Just saying."

Although "Carnaval De Luz" is U2's first album in nearly a decade, the band has stayed busy. Two surprise digital-only EPs, "Days of Ash" and "Easter Lily," each with six songs, appeared for Ash Wednesday and Easter respectively. There is no overlap between the EPs and the new album, meaning U2 will have released 24 songs in a single calendar year by the time "Carnaval De Luz" arrives — a productive way to mark the band's 50th anniversary.

The first single from the album, "Street of Dreams," came out in July, before the project was officially announced.

The full track listing:

• Go (Carnaval De Luz)
• La Reina
• Street Of Dreams
• The Mirror Maker (Rosalía)
• Superficiality
• If The World Is At War We Better Not Be
• Silencio
• The Greatest Show On Earth
• Glorify
• Midnight Sunshine
• Can't Stop Us Now
• Torn (Feat. Dolly Parton)

With "Torn" billed as Parton's final recorded vocal, the album's closing track now carries weight far beyond U2's own catalog — a farewell performance placed, deliberately, at the end of the record.
