Overture (Hazbin Hotel)

Taking place one week after the events of the series' pilot, Princess Charlie Morningstar of Hell (voiced by Erika Henningsen)[5] reveals in a backstory that her father Lucifer was originally an angel, who fell in love with Lilith, the first woman.

As Angel Dust (voiced by Blake Roman), a patron at the hotel, wonders why it is being moved forward, Lute shows the corpse of an exterminator killed in Hell the week before to Adam.

[16] A sing-along version of the episode's second song, "Hell is Forever", was released to YouTube by Amazon Prime Video to promote the series on January 20, 2024.

[17] The Geeky Waffle called “Overture” "a beautiful opening salvo for Hazbin Hotel", complimenting the "well-written, unlikable characters" in Adam and Lute, "Brandon Rogers as Katie Killjoy [as] the best casting in the history of ever", and the songwriting of Sam Haft and Andrew Underberg as "stunning".

[18] That Shelf criticized Medrano's "lack of professional experience" in directing the episode, comparing it to "Tumblr fan fiction [with] simultaneously too much forced background exposition establishing a deep lore, and not enough basic explanation of who the characters are and why they’re there".

[22] Seriangelo praised the "captivating guise of arrogant warmongers" in Adam and Lute, whose song "rewards the characterization of the characters and the setting".
