[1][2] Production of the album took place during the COVID-19 pandemic, with the singer deciding to explore new sounds after watching TV shows such as Pose and RuPaul's Drag Race, while also listening to dance songs by Madonna, Whitney Houston and Cece Peniston.

[3][4] A concept album that follows "the progress of a party, from arrival through romantic tension to break-up and final redemption", About Last Night... mixes synth-pop, disco, house and R&B[5] with themes of love, empowerment and confidence.

[15] "Let Love Go" featuring Lil Tecca and "Crying on the Dance Floor" were released as promotional singles from the album on 29 June and 12 July 2022 respectively.

[18] In a critical review for The Line of Best Fit, Dave Russell found the album "almost completely devoid of charisma, uniqueness or nerve" and "smothered under the weight of generic, radio-pandering production and derivative genre cosplay" with "lyrics that are vague to the point of meaninglessness".

[4] In contrast, NME contributor Hannah Mylrea gave the album four out of five stars, stating "'About Last Night...' leaves you with your ears ringing, hooks stuck in your head and a healthy dose of dancefloor catharsis that'll make you feel lighter.
