She has been noted for creating "intimate, anxious indie rock songs [that] wrangle with disappointment and relationship challenges,"[1] with personal and confessional lyrics.

She then grew up in the conservative small town of Spruce Pine, North Carolina, where she and her artist mother, Kimberly Oberhammer, faced difficulty fitting in.

[11] De Souza toured with a full band featuring Dexter Webb (guitar), Zack Kardon (bass), and Avery Sullivan (drums).

De Souza described the concept of "Smog" as revealing her feelings of anxiety about living alone during the COVID-19 pandemic, when everything felt "unknown and distant", and described her emotional state as "delirious joy and a real tired hopelessness".

The title "All This Will End" conveys De Souza's intention to focus on acknowledging but making peace with mortality and inevitable death by celebrating small moments in life.

[15] De Souza will embark on a summer tour in support of the album, has said that she already has material written for another LP, and hopes to explore the pop genre in the future.

[10][18][19][20] Imagery of nature also appears frequently in De Souza's lyrics and concept art, often in contrast to grocery stores or parking lots.

De Souza has explained that she sees grocery stores as a symbol in her life where she feels out of touch with humanity, and that she prefers to connect with the earth and learn from nature.
