"Piano virtuosity can take a variety of forms, but one of the rarest belongs to John O'Conor ... [he] represents a vanishing tradition that favors inner expression and atmosphere over showmanship and bravura ... in technically complex passages he goes the extra measure to find the ideas behind the flurry of notes."
"John O'Conor must be ranked high indeed ... this was exquisite playing - lucid, poised and cool; he gave himself to the expression of this graceful music. This was a memorable concert."
New York Times
"Impeccable technique and musicality ... it would be hard to imagine better performances."
Sunday Times (London)
"O'Conor brought real poetry to his recital of late-period Beethoven ... incisive, even visionary projections that drove to the heart of the musical matter. O'Conor led us with a lucid touch and a keen intellect ... this artist has the kind of flawless touch that makes an audience gasp."
"John O'Conor is a pianist of unbounding sensitivity, and these recordings bear witness to his beguilingly eloquent style."
"John O'Conor, who by now should be recognized as the world's premier Beethoven interpreter, gives each sonata its due, never overworking, always sensitive to expressive possibilities inherent in a melody or suggested by a larger structural scheme."
