Neither guitar hero nor singer metal, OH. invents a progressive rock art metal where Olivia’s guitar is queen, sometimes supplanted by her war cries sung like a second guitar. An extraordinary musical experience, extreme for canterbury fans, so to discover absolutely. ~ Jean-Christophe – Neoprog

What Oh. screams out of her guitar is not for the faint-hearted, by the constant stream of trash riffs this is a dirty Steve Vai or a vicious Joe Satriani but with balls or better said without balls or at least as well. It is unsettling in the metal scene when a longhaired guitarist turns out to be a woman in the end…Her voice meanders from mood to emotion. From fear to love. The songs do not have a standard structure but are textures like the wandering Etesian winds that so often thrash the Aegean Sea. ~Jos Driessen – Progwereld

An excellent example of how instrumental guitar albums can still sound inspired and interesting. – Jupiter Variation

“In 2008 Jannick Top sent a shock wave through progressive rock community with the release of “Infernal Machina”. The sound that he created on that album was absolutely unique, a fascinating collision of zeuhl, metal and primal screams. Now after ten years I found the same formula rediscovered and applied, again with astonishing result, by OH. (Olivia Hadjiioannou) in her new album Metallia.” ~ Tomasz Grzywalski – Secret Exhibition

“The hidden leitmotives and recurring patterns in the compostion reveal themselves only after multiple listens and make this EP a real grower that you will return to over and over again and still be surprised and impressed every time you hear it. With Metallia, Olivia Hadjiioannou has proven to be an incredibly gifted and creative composer and technically talented musician. If you are tired of progressive bands repeating the same old stuff over and over again, look no further – Oh. has you covered.” ~ Matt S. – Metal Soliloquy

“Only after a few passages does the open music lover begin to discover that the pieces are multi-layered and rich in detail and that the electric guitar is only used as one means of expression among many. Besides the parts for the guitars and drums, one discovers the ethnically coloured percussion, the creative rhythms and breaks and the polyphonic, mostly very wild vocals as well as the more extreme and unusual sounds that one can elicit from the human vocal cords. ~ Siggy Zielinski – Babyblauen Seiten

“With top notes of Dream Theater and the intensity of Liquid Tension Experiment, Olivia takes the listener on a dark yet vivid journey that intersects the mind of Edgar Allen Poe and the imagination of Stephen Gammell” ~ Vinny Iacocca – The Closet Concert Arena

“Stunning, raw and uncompromising” ~ Sébastien Bonnays – Prog Female Voices

“Time to tell you about this stratospheric lady who comes from nowhere or from another planet, that of metal-prog-fusion-trash-dream-haunting and not only!” ~ Alain Massard – Profil Prog

“The most important adjective is “powerful”. Everything oozes power. The compositions, the sound effects, the arrangements, the use of dynamics in mixing; everything has received a large dose of attention, creating an epic sound. These elements make a grandiose mix, where nothing stays the same, except the powerful impression that it all leaves.” ~ Jerry Van Kooten – Dutch Progressive Rock Page DPRP

Olivia Hadjiioannou is always up for a surprise… After the quite heavy “Synemotion” album, she released a couple of distinctly art rock oriented singles. However, her latest EP is quite different from everything we have heard of her before: It’s a tour de force into high-grade prog metal realms with shredding guitars, sinister vocal layers, and unexpectedly transforming rhythm patterns. All music composed by Oh. All instruments played by Oh. An overwhelming one-woman show! Favorite track: Androgyny. ~ Sven B. Schreiber – Bandcamp

This girl isn’t afraid to sound unique with this gorgeous, mind expanding instrumental feast of experimental prog metal gifted with shredding riffs, eastern vibes, ethereal interludes and dramatic shifts in pace and complexity. There’s no empty virtuosity here though, since everything flows together into one sonic experience that never ceases to sound warm, emotional and organic. An ambitious and compelling endeavour. Favorite track: Androgyny. ~ Sauro Fabi – Bandcamp

“The whole thing is realized through multi-layered vocals, frenetic but harmonious guitar solos, ecstatic pounding riffs, imaginative violins, rhythmic basses and wild drums. It should Metallia hijack the listener in a wondrous acoustic landscape, which should make him forget everything around him.” ~ Joan Degener – Betreutes Proggen

A symphonic approach for “Dragon’s Kiss”, in truth a melodic melting pot to better blur the tracks, Olivia wanders according to her inspirations and goes from a nostalgic rock to a screaming and fusion metal, revealing an amazing skillfulness. The last “Triumph” track, which is a real slaughter, exudes a great freshness of inspiration and shows, if necessary, the imperial mastery of the lady.Impregnated with a heavy atmosphere, an eclectic and electric music with a fast tempo, this “Métallia” is a very beautiful album where the lovers of Olivia Hadjiioannou and the others will find what they are looking for! ~ Gabriel Badelier – Progcritique

“Time signatures change, bombastic elements come in and out, and it really feels like the listener is being swept along in a maelstrom, or being put inside a washing machine when it is at full pelt.” ~ Kev Rowland – Firebrand radio – Framemusic

“Truly mindblowing. And speaking of mindblowing, here we have a musician that seems to excel at everything she does. Fluent in drumming, bass, guitars, piano and violin!” ~ Peter Cox – Your Music Blog

“She has developed a musical style of her own, which can best be placed in the utmost corner of extreme prog metal” ~ Henric van Essen – Dutch Metal Maniac

“Olivia Hadjiioannou shows us the female side of progressive metal, muscular and aggressive like that of her male colleagues, but the Greek musician is also attracted by the contrasts between primordial chaos and latent tension that this can produce….The music does not stop at progressive metal with a symphonic touch but inside there emerge inflections that point towards Middle Eastern, operatic and Hellenic stylistic elements, all fundamentals that contribute to increase the melodramatic depth of the work. It must not have been easy to design the complex stratifications that make up the pieces in solitude.” ~ Lorenzo Barbagli – Open Magazine

“Olivia begins the Great Work by pouring the devastating fury of the Erinyes into inhuman vocalizations that fully invest the listener, annihilating him definitively with Sabbathian riffs and a killer groove. The sound is repeatedly fractured by acid lashed metal and by a percussive tribalism that the traditional toumperleki dominates, underlining its oriental features.” ~ Antonio Menichella – Hamelin Prog
