Past Lives is the debut studio album by American supergroup L.S. Dunes. It was released on November 11, 2022 by Fantasy Records and distributed through Concord. Three singles preceded the album's release: "Permanent Rebellion", "2022", and "Bombsquad".
 The seeds for L.S. Dunes were sown during rehearsals for Thursday's 2020 Christmas livestream, where guitarists Frank Iero and Travis Stever engaged in "serendipitous, impromptu jam sessions" alongside Thursday bassist Tim Payne and drummer Tucker Rule, where they had an "instantaneous" chemistry. Although there weren't originally plans for an album, the members of L.S. Dunes continued writing songs and convened in person for the first time in mid-2021, with time booked to record at the end of that year.
 The band had fully formed and individually recorded their parts on Past Lives before landing on Anthony Green as a vocalist, who wasn't aware who was in the group when he began recording vocals. Past Lives was produced by Will Yip who tracked the band at his Studio 4 Recording space in Philadelphia. A month before studio time in September, Iero slipped from a ladder and broke his wrist which delayed the session to December.
 Past Lives is a post-hardcore and emo album. The album opens with "2022", a track which originally appeared on Green's solo album Boom. Done. (2022) but was removed from digital versions of the album. It is a "somber" and "hypnotic" song. The song has been described by Green as "the most fucked-up" and "personal" he ever wrote. "Antibodies" is a "frenetic" and "driving" track, which was the first they had completed work on. "Grey Veins" is a "masterful" emo composition with a "massive" chorus, high vocals and "thundering" drums. "Like Forever" features "bouncy, intricate" guitarwork by Stever, while "Blender" has a prominent bassline.
 The album's title track has Green howl the lyric "I'm not all my mistakes, no matter what they say about it...". "It Takes Time" is a "powerful" song, while "Bombsquad" features "garotte-sharp" political observations inspired by Green's disgust with Donald Trump and the January 6 U.S. Capitol attack. "Grifter" is a "chaotic" song, while "Permanent Rebellion" is a "blast" of punk rock with "soaring" guitar work. The album's closer, "Sleep Cult", pays homage to 1950s doo-wop.
 To coincide with the band's formal unveiling, the album was made available for pre-order and its cover art and track listing was announced, along with the release of "Permanent Rebellion" and its accompanying music video as the album's lead single on August 26, 2022. "2022 was released as the second single on September 23, 2022. "Bombsquad" was released as the third single on October 21, 2022, alongside a live video of a performance at Dreamland Studios in Woodstock, New York.
 Past Lives was released on November 11, 2022 by Fantasy Records and distributed through Concord. To support the album's release, YouTube Music advertised Past Lives on the Nashville Sign billboard.
 Past Lives received positive reviews from music critics. At Metacritic, which assigns a weighted mean rating out of 100 to reviews from mainstream critics, the album received an average score of 74, based on six reviews. BrooklynVegan's Andrew Sacher opined that the album "exceeds expectations" for a supergroup, characterizing it as "personal, impactful music". Sam Law of Kerrang! thought the tracks contained "flickers of familiarity" that were "in service of breaking new ground". Writing for Dork, Rob Mair praised Green's "typically powerful performance" but criticized the songs "Blender" and "2022" for being more "pedestrian" than others.
