"O’Brien, performing here solo as Jeen … provides us with this week’s mantra ‘burn it bright’ … wistful and breezy" – NPR
"danceable indie pop" – Brooklyn Vegan
"Jeen has that old-timey alt-rock/punky vibe going on that just makes you want to blast her album really loud" – Buzznet
"...has echoes of bands like The Breeders and other 90s female fronted alternative acts in the scratchy texture of her voice and the reverb-fueled jangle of her guitars" – Baeble
"...with a drumbeat and a catchy vocal that makes this sound… ripe for singing and clapping along to in a live setting" – PopMatters.
