"All Falls Down" is a song by British-Norwegian DJ and record producer Alan Walker, British DJ and producer Digital Farm Animals and American singer Noah Cyrus, and featuring Swedish singer Juliander. It was composed by Digital Farm Animals, Pablo Bowman, Sarah Blanchard and its producers Walker, Mood Melodies, Digital Farm Animals and the Six, with lyrics written by the Six, Bowman, Blanchard and Daniel Boyle. The song was released on 27 October 2017 via Mer Musikk and Ultra Music to mixed reviews from critics, who praised Cyrus's vocals but deemed the song inferior to Walker's previous songs.
On 23 October 2017, Walker released a trailer for the single. Described as "an action-packed adventure of epic proportion" and "a real roller coaster affair" by critics, it features a variety of subplots, including romance, kidnapping, cult-like burials, "an Alan Walker-branded time capsule and explosions", as well as "flaming torches, desert landscapes, welded metal and a digital timer". On 25 October 2017, Walker revealed features on the song via social media.
Walker offered in a press release: "With this record I got the opportunity to collaborate with some amazing artists. Noah Cyrus' voice is absolutely incredible! Ever since I first heard the topline, I've been in love with it and can't wait for my fans to hear it as well. It has a refreshing production that still fits well within my signature sound, which is important for me to maintain as I evolve as an artist." Cyrus added: "I've loved this record since the moment I heard it. It's amazing to be a part of this song with such a badass dude and it's really incredible to be a part of this project."
Kat Bein of Billboard wrote: "The track kicks off with glimmering acoustic strums and finger-snaps, all leading up to a bouncy, anthemic drop." Matthew Meadow of Your EDM felt "the drop is still characteristically Walker", and appreciates that "the influence from [Digital Farm Animals] is noticeable". Kevin Apaza of Direct Lyrics praised Walker for "gives listeners a counterbalance in the form of an uplifting electro pop beat and drops" despite the "rather sad" lyrics. Erik of EDM Sauce wrote a mixed review of the song, saying that the song has "a more laid back almost tropical feeling", which he opined as "something like Kygo might release". He also praised Cyrus for "providing gorgeous vocals throughout". He concluded by deeming the song "a lesser known, forgettable release" from Walker. Olav Haraldsen Roen of NRK P3 said, "The verses are dry and raw, and the chorus, despite Walker's signature pulsating synths and a simple melody line, is quite characterless."
The music video, released alongside the single, joins a post-apocalyptic trilogy which began with the visual for Walker's previous single "Tired". It continues where the previous video left off, taking place eighty-three years after a solar storm destroyed all technology on Earth in 2017.
The music video was shot in Bosnia and Herzegovina, Croatia and Montenegro. Some of the filming took place at the Kupari Tourist Complex, a ruined resort in à ½upa DubrovaÃÂka, Croatia.
In December 2017, Walker performed "All Falls Down" with Noah Cyrus and Juliander at YouTube Space NY to celebrate Walker's YouTube channel reaching 10 million subscribers. On January 11, 2018, Walker appeared with Cyrus on The Tonight Show Starring Jimmy Fallon, where she performed "All Falls Down" with their band. Walker told Nordic music magazine Gaffa: "I'm really looking forward to performing on "The Tonight Show" with Noah Cyrus! I've seen the program and many performances before, and it's great to be on the same stage myself. I hope people back home in Norway check it out on TV and online, and that they like what they see".
