"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 

"A sounds somewhere between Indigo De Souza, Frankie Cosmos and Soccer Mommy. The collection of new sound-bending tracks of the indie rock persuasion are a widespread success." Periphery Magazine describing Can't Have it All and Evolving

"Neptune's Core dishes out fun and incredibly catchy songs with a strong range. Elements of pop punk and even alt-country find themselves infused in their sound. Turning Red is pure pop ballad while Drowning takes you down an indie rock road toward a boisterous second half full of pounding drums and blisteringly strong vocals. Every track offers something different and inviting, giving you a ton to appreciate from these four great musicians. Third Coast Review  reviewing Evolving

"If you like Olivia Rodrigo but would like to find an artist in a similar vein whose music goes a little "harder", Neptune's Core might be a band you'd like to keep under your belt. Their sound embodies the chaos of the dreary place between being a teenager and an adult. The loud instruments and wistful vocals lay the base of each song. Their album Evolving shows a natural inclination to mix fuzzy instruments with breezy vocals that tie the album together in a very cohesive way. The shoe gaze influence blended with the alternative references mirror their lyrics perfectly. A band who makes you feel seen and heard and holds your hand through your adolescent years." Janset Yasar founder and editor-in-chief of reviewing Evolving 

 “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.

"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

“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
