“From the first note, "Not Ready" captivates with its stunning combination of beautiful plucking and soft, driving drums. The song exudes a folky warmth, drawing listeners into its intimate embrace. Keller's vocals, imbued with a haunting quality, add depth and emotion to the already poignant lyrics.”
Unheard Gems

“An intercontinental piece produced by US-based Dominic Romano, ‘Not Ready’ brings kaleidoscopic intensity to the simplicity of folk music. A guitar-driven single, there is a soothing nature to the folk song; however, Thomas LaVine’s underlying drums bring an edginess to the soft tone – as if a heart pulsating beneath a mystical soul. Keller’s obscure vocals always remind me of a mystical siren running through a dark forest. Always a fantastical whisper of song, but simultaneously a bold and commanding rush of dulcet vocals; Keller showcases the power of a whisper in ‘Not Ready’.”

With absolutely beautiful and wonderfully captivating soundscape, she lets her voice come alive and pull us in from the moment we press play. She also embraces the lyrics fully, making sure the feelings and emotions that are part of them resonate with all who listen from start to end in a natural and palpable fashion.

"É uma canção emocionalmente carregada, é certo, mas com uma energia gritante e raios de luz que não nos deixam ir abaixo. A melodia chega-nos fluída, crescente, mais suaves nos versos e mais vibrante por alturas do refrão, cheia de harmonias vivas e de acordes calorosos. Confesso que me rendi à progressão das linhas de guitarra, dedilhadas e luminosas, que, acompanhadas por banjo e sintetizadores, resultam num ambiente cativante."

“Esta canción nos recibe con una combinación íntima entre una guitarra brillante y una voz profunda la cual nos va guiando a través de una narrativa llena de emociones, pero sobretodo empatía, conforme avanza la canción en la base rítmica suma un dinamismo profundo e interesante a la narrativa de la canción, mientras que una atmósfera discreta pero expansiva hace que las emociones a su vez crezcan y sean transmitidas de forma natural a los oídos y corazones de los oyentes.”

“I am a fan of Luna Keller's enchanting vocals and ethereal-like harmonies that effortlessly create such a warm, comforting atmosphere that allows for her storytelling to soar. You can clearly feel the emotion pouring from her delivery, instantly connecting us to her powerful declaration of the will to fight and live through her mental health battles. A relatable storytelling that is enhanced by a dynamic production that pairs her gorgeous vocals with killer drums (played by Thomas LaVine) seamlessly paired with cool guitar plucks and echoing harmonies.”

“Inner battles, that's the subject of this concept album that classifies in chronological order the stages one may go through when our mind and body are no longer in agreement. "Not Ready" is, one might say, the chapter where everything changes. And the music video illustrates very well this logical sequence of stages, where we can see Luna chained by ropes to trees in the middle of the forest, fighting with this certain death standing in front of her.

Fortunately, whether in this very realistic illustration or in real life, Luna survives and ultimately escapes her grim fate. And we are indeed glad that this is the case so she can now tell us this incredible story, with the talent we know she has.

Do I still need to remind you of the precision with which Luna works? Whether visually or musically, her talent is pushed to the extreme, starting with the writing, and that haunting line: "How do I end this pain without ending myself?"
Indie Music Center

“Her latest is titled Not Ready and marks a turning point in the album’s journey, moving from drowning in depression and mental health struggles to finding the will to fight, and reaching out for support. In the track, Luna captures both the light and the dark of the moment beautifully, and the emotion comes through strongly in its delicate, nuanced and slow-building instrumental, and her ever-expressive vocals.”

“Ich liebe es, auf welche kreative Art und Weise die in Köln beheimatete Singer-Songwriterin Luna Keller ihre Artworks und Musik kreiert. Nach einigen Vorstellungen möchten wir auch ihr heute erschienenes Werk ‘Not Ready’ hier bzw. auf unserer Playlist mit euch teilen. Eine wunderbare Folk Produktion mit wahrhaftig schönen Melodien sowie einer unverkennbaren Stimme im Fokus.”
Berlin On air

“She’s made it very easy to lose yourself within her sound. Not only is the subject matter deeply relatable, but Keller’s managed to make her music sound as though you’re having a private conversation with someone who trusts you completely with the entire contents of their heart. And as she reaches into her falsetto for the refrain, it is truly enough to bring you to tears, particularly if you, too, have traversed the darkness of mental/ emotional desolation.”
