"A beautifull interpretation."
(Gurdjieff International Review)

"Hidden Sources contains the most representative and best selection of the Gurdjieff / de Hartmann music I've heard on a single CD. Alessandra Celletti's interpretations are as sensitive and as idiosyncratic as Glen Gould's. Her playing and selection are exceptional."
[J. Walter Driscoll - Editor of Gurdjieff International Review and author of "Gurdjieff: an annotated bibliography" (1985) and "Gurdjieff: a reading Guide" (1999)]

"Hidden Sources offers a sensitive and even tender interpretation of the Gurdjieff/deHartmann music, which calls for a rare quality of surrender to the music combined with a precision of intention. This music is both simple and extraordinarily subtle; and Alessandra Celletti's touch reflects these same qualities."
[Jacob Needleman- Professor of philosophy at San Francisco State University and the author of many books, including "Time and the Soul" and "Lost Christianity"]

Beautiful and inspiring!
[Charles T. Tart - Professor, Institute of Transpersonal Psychology, Palo Alto, California]

"Whether chosen through natural or intentional selection, the pieces in this album are woven together in a musical tapestry that Celletti shares wholeheartedly with you the listener. Hidden Sources is a gentle but strong expression of an artist approaching a mystery. We hope Alessandra Celletti continues on her way with this music".
[James Tomarelli - editor of Bennett Books]

"Cells of beauty and not verbal wisdom that speak clearly to our deeper soul. Every note carves a profile, designs a curve, each key reveals a mountain, a cheekbone, a perfume, a spiritual landscape. Sacred dances for sceptical travellers of knowledge. Immense."
[Marco Boccitto - musical reviewer of Il Manifesto]

"Alessandra Celletti's touch gives a specific emotional colour to every note,to every passage, to each of the 18 tracks of the disc, western interpretations of Asian and Indian songs. A bare and essential musical reading enhances in every passage the top level writing of the two composers."
[Paolo De Bernardin - musical reviewer of Musica! La Repubblica]

"This music reveals the Hidden Sources of sounds lost, and found again. This "recherche du son perdu" of a lost music contains, within the vital melancholy expressed by the sounds and the performer, an extraordinary light and vibration".
[Erasmo Valente - musical reviewer of L’Unità]

"Hidden Sources is an excellent CD. The all production is superb and Alessandra Celletti plays like piano magician".
[Thomas Tamvakos - ARCHIVE OF GREEK CLASSICAL COMPOSERS]
