About ilomilo

"Ilomilo" (stylized in all lowercase) is a song by American singer Billie Eilish from her debut studio album, When We All Fall Asleep, Where Do We Go? (2019). The song was sent to Italian contemporary hit radio stations on April 10, 2020, by Universal Music Group, and later to US alternative radio on May 26 through Darkroom and Interscope Records, as the album's seventh and final single. Eilish and her brother Finneas O'Connell co-wrote it, while the latter handled the production. Musically an electropop, electronic, and industrial track with ska-influenced instrumentation, the song was heavily inspired by the puzzle video game of the same name. The track also references "Bury a Friend", its predecessor on the album track list.

Eilish's lyrics address several topics including the fear of separation, while her distorted and stuttering voice is sung over a similarly deformed bass. For promotional purposes, the song was performed live during Eilish's 2019 When We All Fall Asleep Tour and her Where Do We Go? World Tour in 2020. On April 24, 2020, an animated visualizer was released for the song. When the album When We All Fall Asleep, Where Do We Go? became available, the song reached number 62 on the US Billboard Hot 100 and charted within the top 40 in Canada and Australia. It was certified gold in each of these countries.
