“O’Brien, performing here solo as Jeen, offers a hybrid Sharon Van Etten/Lisa Loeb ’90s… wistful and breezy” – NPR

“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

“a quick, curious piece of indie rock that seems to be bred for any college-rock station.” – Magnet

“with a drumbeat and a catchy vocal that makes this sound… ripe for singing and clapping along to in a live setting” – PopMatters
