“glacially beautiful... luminous”

— Alex Ross , The New Yorker Just Constellations

“Revelation should prove to be one of the most influential piano compositions of the 21st century.”

— Frank J. Oteri , NewMusicBox / American Music Center Revelation

“An indisputable landmark in Western tuning's circuitous history.”

— Kyle Gann , The Village Voice Revelation / Harmonic Piano

“a new harmonic world began to assert itself.”

— Paul Griffiths , The New York Times Revelation

“An American maverick.”

— Philip Glass

“Revelation belongs among the exhaustive modern masterpieces for solo piano, resting securely at the same level as Hindemith's Ludus Tonalis, Shostakovich's Preludes and Fugues, Cage's Sonatas & Interludes, Duckworth's Time Curve Preludes, and La Monte Young's The Well-Tuned Piano.”

— Richard Kostelanetz Revelation

“music of positively intoxicating beauty.”

— Steve Smith , The New Yorker Seven Sacred Names

“The results are often wondrous. In the midst of clouds of dense clusters rapidly drummed in the bass end of the instrument, an astute listener can perceive high ghost tones - sometimes bell-like, at other times vaporous - as if a choir of angels were singing along.”

— Stuart Isacoff Revelation

“…a virtuosic tour-de-force… Say it plainly — Michael Harrison's Revelation: Music in Pure Intonation is probably the most brilliant and original extended composition for solo piano since the early works of Frederic Rzewski three decades ago. What could have been a mere glossary of unfamiliar sonorities turned instead into a virtuosic tour-de-force that would have done credit to the hypothetical team of Franz Liszt and Claude Debussy working overtime.”

— Tim Page , Spoleto Festival USA Revelation

“The music, with its blend of East and West, soars in interlocking swirls of color, rests in a central chorale and builds steam to an ecstatic conclusion, sounding as if it has always been here.”

— Tom Huizenga , NPR Just Ancient Loops

“Harrison gives the piano a versatility of sound never heard before, ranging from harp to guitar to sitar.”

— Annie Bergen , WQXR, New York From Ancient Worlds

“Built of long, slow notes over ambient sounds, it created a mesmerizing meditative soundspace and a palpable sense of expectation.”

— Arlene & Larry Dunn , I Care If You Listen Radians Phase II

“One long intoxication… As soon as the first notes sound, you know: the piano sounds very different from what we are used to. In a certain way more natural, more organic, whereby the sound resembles bells and clocks… when he stops, we hear those overtones fade out very slowly. A wonderful moment.”

— Ben Taffijin , Nieuwe Noten Revelation

“The best of both worlds: the delectable just-tuned piano sound with the ability of harmonic motion found in traditional classical works.”

— Bob Reina , Stereophile From Ancient Worlds

“A monumental work… the pulsing, gamelan-like waves Harrison conjures from his customized 'harmonic piano' have a hypnotic effect… Revelation sounds like a lullaby that would put only a mad scientist to sleep.”

— Bradley Bambarger , The Star-Ledger Revelation

“Long, sustained pitches — combined with minimal vibrato and keenly accurate intonation — produced a pleasing minimalist drone, for an otherworldly excursion into the farthest reaches of the string universe.”

— Bruce Hodges , The Strad Harmonic Constellations

“The word 'unique' is overused in the contemporary music world. But in the case of composer Michael Harrison and cellist Maya Beiser, the descriptor is deserved.”

— Chloe Veltman , WQXR / Q2 Time Loops

“If the walls of an ancient European cathedral or Middle Eastern monastery could sing, this is what you'd hear.”

— C.W. Vrtacek , The Advocate From Ancient Worlds

“As Michael Harrison has pressed further into the map of his musical life, something magical has happened. The map is folding in on itself, with the seemingly distant now adjacent regions overlapping, simple lines becoming multi-dimensional.”

— David Dies , I Care If You Listen Cello Constellations

“Michael Harrison's Just Constellations explored the opposite of reckless heterogeneity. Influenced by seminal minimalist La Monte Young, the music isn't repetitive so much as it settles onto a single chord and evolves so subtly it's like watching a landscape in changing light.”

— David Patrick Stearns , The Philadelphia Inquirer Just Constellations

“Jaunpuri is a mesmerizing piece, a nocturnal raga of Hindustani classical music, animated by an irresistible wave movement… A wonder! Hijaz Prelude… can be considered as forming a diptych with the previous, yet it is more internalized and structured on more audible loops. A second wonder!”

— Inactuelles Musiques Singulieres , Inactuelles Musiques Singulieres Histories

“This hour-plus trance-inducing solo piano work is a vast experiment in 'pure intonation.' Using an original tuning for the piano, Harrison makes it hum and vibrate in ways that sound both ancient and modern.”

— Jeremy Eichler , The Boston Globe Revelation

“An inventive composer whose works contain echoes of contemporary and Oriental music all in the service of an engaging melodic gift.”

— John Schaefer , New Sounds, WNYC

“The tuning system and modified strings transform the piano's sound, creating a strangely 'Eastern' timbre, with sustained overtones.”

— Jon Andrews , Downbeat From Ancient Worlds

“Revelation is one of the first great musical pieces of the 21st century.”

— Joseph Shaw , The Southampton Press Revelation

“If there really is a music of the spheres, the sound of a fundamental harmony in the universe, it has to be Just Ancient Loops… it propels viewers through time and space, landing them in the present, elated.”

— Kevin Berger , Nautilus Just Ancient Loops

“You play the vividly specific, spine-chilling intervals on Harrison's 'just' piano, and then everything sounds so bland and washed-out and arbitrary and disappointing on the conventionally tuned one.”

— Kyle Gann , The Village Voice Revelation

“…the kind of finely shaded spectrum we might achieve in the third millennium.”

— Kyle Gann , The Village Voice From Ancient Worlds

“Harrison will bring the beauty of just intonation to all lands.”

— La Monte Young

“Harrison has perfected a way of playing in just intonation at the piano… such celestial resonance that it captures your attention from the first note.”

— Linda Kohanov , CD Review From Ancient Worlds

“Jaunpuri is based on a traditional Indian raga, but shaped with Western compositional notation, structures, and harmony. An embellished piano melody twirls and spins through a buzzing tabla and tanpura trance, building in intensity until the circling rhythmic cycles spin out into a breathtaking rhapsody.”

— Maggie Molloy Histories

“The results are gorgeous; sonorous long tones glide in ever shifting harmonic combinations, each of which hang patiently in the air.”

— Peter Margasak , Bandcamp Just Constellations

“"Harp of Yaman" showcases Harrison's skills as a player, in the process confirming that the empty space that seems to envelop these compositions is due to deliberate self-imposed limitations and creative restraint.”

— Randall Roberts , In Sheep's Clothing Hi-Fi Christina Vantzou, Michael Harrison & John Also Bennett

“The Bang on a Can Marathon is always good for a spectacle or two. The day's glitziest work was Michael Harrison's Just Ancient Loops, which cellist Maya Beiser performed along with some 20 electronic versions of herself and accompanying video work by Bill Morrison.”

— Richard Gehr , The Village Voice Just Ancient Loops

“Lovely and hypnotic. Michael Harrison's Harmonic Constellations pairs the live violin with a prerecorded part of both violin tracks and sine-tones… The result, over its 20-plus minutes, is lovely and hypnotic.”

— Robert Carl , Fanfare Harmonic Constellations

“Glorious clouds of harmonics, …divine thunder, angel choirs, celestial bells.”

— Sandy McCroskey , The Nation Revelation

“It is mesmerizing! The tuning is certainly a revelation.”

— Seymour Bernstein

“…an exalting, almost breathless new plane… Its power builds with unstoppable force, deepening and expanding with irresistible energy, and by the climax Beiser was filling the hall with a vast ecstatic ocean of sound.”

— Stephen Brookes , The Washington Post Just Ancient Loops

“The intelligent discrimination with which he approaches his work is something that I have heard only in a tiny handful of classical recordings starting with Glenn Gould.”

— Stephen Hill , National Public Radio Revelation

“Pulling it off was a serious challenge requiring discipline, a willingness to take risks, and real grit. The result was simply exhilarating.”

— Stuart Isacoff , The Wall Street Journal Galapagos in C

“must-hear album for fans of a cappella music.”

— Ted Gioia Just Constellations

“Harrison is bound to profoundly influence the musicians of his generation.”

— Terry Riley

“Harrison is 'like a magician setting up a trick.' He transforms overtones, welcomes their clashes, and keeps his audience surprised and thoroughly captivated, taking them on a tour of beautiful and exotic 'non-Euclidean musical worlds.'”

— The Week , The Week Revelation

“an off-ramp from reality... precisely blended singing and swirling 'halos' of reverberant sound.”

— Tom Huizenga , NPR Just Constellations

“'The Opening Constellation' section proved particularly arresting, a celestial soundscape of gorgeous harmonies that became even more alluringly ambiguous in the ensuing 'Romantic Constellation.' In the concluding 'Acoustic Constellations,' the notes rang out like a jubilantly microtonal choir of bells.”

— Vivien Schweitzer , The New York Times Just Constellations
