"[4] James Skinner of BBC Music said that this method resulted in "something that’s often otherworldly: washed-out and languid, frayed edges combining to create a beguiling whole; fuzzy arpeggios ringing out over washes of synth and electronica, electric guitars and live drums.

"[4] Jon Parales termed the music as both neo-psychedelia and french pop and also considered the album an "anachronistic daydream of loops and live instruments.

[14] The standalone digital release in 2013 featured the B-side "Je Me Perds de Vue", a song which appeared "reversed and warped" on Melody's Echo Chamber as "IsThatWhatYouSaid", and which had since been restored.

[14] The band's first ever headline show was held at Cargo in London, England on 6 November,[16] prior to a 14-date French and UK tour that took place from 8 December 2012 to 5 March 2013.

[2] In a review for Drowned in Sound, Dom Gourlay said that "while there are comparisons to be made with artists of [shoegazing] both old and new, Melody's Echo Chamber has much more to offer than being a mere revisionist exercise".

Gourlay also noted similarities to Kevin Shields and My Bloody Valentine's Loveless with Parker's production, and added that "the future possibilities for [Prochet] and Melody's Echo Chamber are endless … they've conjured up one of 2012's… finest debuts.

[4] Some reviewers were critical of the album's latter half,[3][26] With Jordan Blum of PopMatters writing that its "synthesis of 1960s hippie female songwriters and eccentric production masters… gets a bit repetitive by the end, but it's almost indisputable to say that Prochet offers some charismatic melodies … and interesting sounds along the way".

[33][34][35] Tim Sendra of AllMusic wrote that "Unfold serves as a wonderfully hypnotic and spacey bridge between Melody Prochet's debut LP and her later work like the near-perfect psychedelic epic Bon Voyage… While she and Parker made a good team, it's clear she had some exploring to do on her own, and this was an important first step.
