"[5][6][7] On 11 June 2024, Berwyn announced the album's track list and release date, alongside the third single, "Dear Immigration.

[10] Ed Lawson of DIY described it as a "record that's as skilled in pop immediacy as it is emotional expression; a lyrical gaze that looks as deeply inside as out" and Berwyn "an artist who, on this debut album, can seemingly do just about anything".

[11] Ben Devlin of MusicOMH characterised Who Am I as "a relatively brief selection of tracks [that] contains a lot of autobiographical heft, as he works through topics of race, insecurity and excess over surprisingly versatile production".

[12] The Observer's Damien Morris wrote that it "cuts a prickly path between the experimental rawness of Mercury-nominated mixtape Demotape/Vega and its excellent sequel Tape 2/Fomalhaut's smoother entreaties" as well as remarking that "the ferocity of Berwyn's talent and the piercing beauty of his crackling, folk-R&B croon mean these heavy topics are never a burden".

[13] Reviewing the album for The Skinny, Rhys Morgan called it "declarative" as "the candid expression of his previous work remains, now finessed into a towering major label debut".
