Song history written by TimelandIsWacky
“Lonely Cosmos” is one of a few songs on Phantom Island about homesickness, though its vast space setting makes it the most tragic. We hear of an astronaut flying further and further away from Earth, getting older and older. Throughout their trip they think existentially about the universe – questioning if humanity is alone and fearing their death within the infinite universe, though they eventually come to the realization that they’re only stardust. The song ends 620 light-years away with the astronaut sending mail back to their parents. They say that while they’ve seen something as extraordinary as the edge of the Milky Way galaxy, they still miss home (it’s possible to connect these lyrics to “Kepler-22b” as the planet is 620 light-years away from Earth according to the NOAA, though other sources have different estimates).
Alongside the space-themed lyrics, “Lonely Cosmos” features some of the most adventurous arrangements on Phantom Island – especially with its surreal intro and haunting outro. Chad Kelly’s work was so heavy on the orchestra that Stu went as far as to say it surprised him.
While not much is known on the recording of Phantom Island, Stu explained the process behind the orchestral elements of “Lonely Cosmos” to the Sydney Morning Herald. “...if you look at the charts, they are written in a strange way where he’s telling the strings players to play a little out of time and a little out of tune with each other. We then had the strings play over themselves and overdub over themselves quite a few times. It just kind of created a cool, three-dimensional atmosphere.”
The song was written and performed by Ambrose (vocals), Cavs (drums/percussion), Cook (bass/vocals), Joey (guitar) and Stu (bass/guitar/Mellotron/vocals). While no footage of the recording sessions were released, the song was featured in The Making of Phantom Island, with a full release on Phantom Island on June 13th, 2025.
“Lonely Cosmos”made its live debut during the band’s first orchestral show at the TD Pavilion at the Mann on 2025-07-28 and would be played at every other orchestral show that year. The live arrangement was similar to the studio arrangement though it featured a more prominent harp part. Stu also opted to use his Yamaha SG-A2 instead of an acoustic guitar for the song, giving “Lonely Cosmos” a bit more edge than what was heard on Phantom Island.
