[1] "Hollow" was written and composed by Dons, Kate Northrop, and Liam Geddes during a songwriting camp in Spain.

[4] In interviews with Wiwibloggs' William Lee Adams, Dons says that the song explores how one's "insecurities can hold us hostage", with others trying to dictate on how a person should live.

[19] Scotsman writer Erin Adam wrote a neutral review, rating the song six points out of 10 and stating that it was an "unshowy, but a good, honest pop ballad".

[20] Latvia's broadcaster Latvijas Televīzija (LTV) organized a 15-entry competition, Supernova 2024, to select its entrant for the Eurovision Song Contest 2024.

[24] At the end of the final on 10 February, the song was announced to have won both the televote and the jury vote, winning the competition.

During the allocation draw on 30 January 2024, Latvia was drawn to compete in the second semi-final, performing in the second half of the show.

[26] Dons was later drawn to perform ninth in the semi-final, ahead of Armenia's Ladaniva and before San Marino's Megara.

[27] For its Eurovision performance, Dons wore a blue, sleeveless pantsuit, with a large circular prop accompanying the stage with him.

[29] Despite bookmakers having Latvia lowest in the odds to qualify, "Hollow" finished in seventh, scoring 72 points and securing a position in the grand final.
