Heaven :x: Hell[a] is the eighth and final studio album by Canadian rock band Sum 41, released on March 29, 2024, through Rise Records.

On March 23, 2022, the band announced the album and its musical styles, with the "Heaven" side throwing back to their earlier pop punk style, and the "Hell" side continuing their recent heavier metal sound.

[11] On September 19, 2023, it was announced that Whibley was hospitalized for COVID-19,[12] and pneumonia, which led to the risk of heart failure.

[18] The lead single, "Landmines", was released on September 27, 2023, along with a music video and the announcement of their signing to Rise Records.

[33] Neil Z. Yeung of AllMusic wrote that the Heaven side of the album "[finds] the sweet spot among Billy Talent, Green Day, and Blink-182," while the Hell side is similar to 2016's 13 Voices and 2019's Order in Decline as it is an "emotionally charged whirlpool of rage and frustration.

"[35] Charlotte Griffiths of Distorted Sound Magazine called the album a "perfect goodbye from such an iconic band.

[37] Rishi Shah writing for NME described the album as a "pot of soundscapes cherry-picked from their career," and a "fitting last hurrah for a band" but had some criticisms for songs like "I Don't Need Anyone" and "House of Liars".

"[29] Mercedes Chircop of Spill Magazine called the album "impeccably crafted" and said that "despite [the] distinct sounds [of Heaven and Hell], both sides remain unmistakably Sum 41.

"[39] According to Sputnikmusic, the album is "emblematic of who they are, showcases their greatest strengths, and represents their most popular eras as a band.

"[28] According to Paul Brown of Wall of sound, "[the album is] packed full of punchy, high-octane punk jams and tear-inducing, shred-filled metal anthems that'll withstand the test of time and remind us of the calibre of talent this band produced in their 28-year long journey.
