After recording music in his bedroom at the start of the COVID-19 pandemic, Glaive became a leading force of the hyperpop genre and signed a deal with Interscope in October 2020.

Cypress Grove gained Glaive a global fanbase and received widespread critical acclaim; several publications featured its lead single "Astrid" on their year-end lists.

[8] Carrie Battan of The New Yorker called it "polished" and wrote that it pulls sounds from alternative rock, hip hop, electronic, and pop music.

The Fader's Alex Robert Ross said it is one of Glaive's "poppier" songs and contains "a synth line that would fit just as well on Katy Perry as it might on contemporaries like OSQuinn".

[7] The track is built around a guitar line and contains "glittering" electronics, a footwork-sounding kick drum, pitched-up melodies, and a minimal chorus.

[14][15] "DND" is a Midwest emo-inspired hyperpop song[16] that targets the people who started talking to Glaive only after he begun making music.

[17] When writing about "Hey Hi HYD", Pitchfork's Julia Gray said Glaive got away with the song's title "due to the force of his charisma rather than his age".

[18] Cypress Grove gained Glaive a global fanbase[19] and, according to Tyler Damara Kelly of The Line of Best Fit, it received widespread critical acclaim.

[20] Writing for The Fader, Ross said the EP positioned Glaive "as the most promising kid in pop music" and called him "a naturally gifted songwriter".

[7] In a review of Glaive's 2021 EP All Dogs Go to Heaven for Pitchfork, Gray retrospectively called Cypress Grove "an impressive snapshot of modern adolescence".
