Lyrically, In Loving Memory described Blackbear tackling subjects such as the loss of his father in 2021, parenthood, and mental health. He further described it in an interview with Alternative Press:[1]
The whole idea behind the album is [a] letter to my father who passed away, and I never got to say goodbye. I’m making this music that is true to my roots, and I’m bringing out guest stars like Jordan Pundik from New Found Glory and Bert McCracken from the Used. I’m paying homage to the bands I grew up listening to with this album.
