"Their age belies the sophistication of the songwriting and instrumentation... classic alternative era with delicate fragile quiet moments exploding into loud dynamics... I hear some Soccer Mommy and Snail Mail influences but what I don't hear are artists still in their teens" Jim DeRogatis, Sound Opinions reviewing the Evolving album as a Buried Treasure 

“A triumph… best described as a cross-between alt-rock and singer-songwriter tunes with strong harmonies… like a mix of Soccer Mommy, Fiona Apple, The Bangles, and Vivian Girls with smart arrangements and terrific lead vocals… powerful indie rock that transcends their youth… echoes the sound of great women’s rock like Courtney Barnett… such a pleasant surprise.” WCXP CHIRP Radio 107.1 describing Neptune’s Core and Can’t Have it All

"Jangle-y indie pop that sometimes goes fuzzy and grunge-y... a solid debut album" OhMyRockness NY/LA/Chicago describing Neptune's Core and Can't Have it All

 “A revolutionary talent that deserves to be heard. An early ‘90s grunge haze is present through the jangled guitar riffs, emphatic drums, and passionate vocal harmonies delivering captivating lyrics that speak to a new generation through their storytelling abilities. Had me remembering the early days of Soccer Mommy and Snail Mail.” A1234 Music reviewing Neptune’s Core’s album Can’t Have it All.

“Classic songcraft and tight harmonies… an absorbing rumination on attraction” Songwriting Magazine UK reviewing the song Turning Red

“ Why not join the bandwagon early and support this fantastic upcoming band! Their two 2021 singles, Turning Red and Shot in the Heart are pristine indie rock jams that should be on everyone’s playlist by now!” Third Coast Review
