"A voice, a real voice, with beautifully welded registers, a sumptuous timbre (simultaneously charming and sensuous), solid, fiery lower tones and powerful highs, which enrich a singing line admirably sustained by a flawless legato.
"In the formidable 'Wesendonk Lieder' of Richard Wagner, delivered without bombast, with suppleness and lyricism (and yet a gripping intensity), Kimball Wheeler sings with all her heart. One is happily seduced; completely won over; and moved to tears. Kimball Wheeler: an excellent singer, and perhaps soon, if we're lucky, a star."
"Kimball Wheeler is everything but a typical recitalist. Her large, beautifully projecting Mezzo doesn't deny her theater experience as an interpreter of Wagner and Strauss; she doesn't artificially alter her instrument, but always sings with full vocal commitment. Although linguistic clarity is very important to her, it is not the central point of the performance. The voice always stands in the foreground: the radiant, expressive voice.
Her timbre is pleasantly silky, and especially in the middle range, colorful and flexible. The high range is beautiful and brilliant.
"Of course, the program for the evening consisted of everything except sure-fire winners. Four extraordinarily interesting pieces by Henri Duparc were followed by the funny and refreshingly intelligent 'Histoires naturelles' by Maurice Ravel. Five songs by Charles Ives were performed with beauty and precision. A group of Brahms songs, sung with melancholic incantation, formed not a showy corsage, but a noble bouquet. And the world premiere of Songs without words by Dimitri Terzakis, for unaccompanied voice, provided an unparalleled challenge. It speaks for Kimball Wheeler that she had her strongest moments, vocally and interpretively, in these simultaneously new and stone-age sounding pieces. One could imagine them as laments in an ancient desert landscape. Her performance took us on a journey back to the origins of singing; indeed of music itself."
Recital, Düsseldorf Tonhalle
"The 'Urlicht' ('primeval light') was interpreted with enormous depth of feeling by Kimball Wheeler, mezzo-soprano. Intoning with shadowy vocal colors, she took us out of this world."
Mahler Symphony #2 , Düsseldorf Symphony
"Kimball Wheeler, a true Verdi mezzo-soprano, convinced through the many faceted scope of her voice's expressiveness. A peak moment was the 'Lux Aeterna,' in which her singing painted landscapes of musical paradise."
Verdi Requiem, Jena Philharmonic
"Kimball Wheeler is ideally cast and the performance is committed and vividly recorded."
Lees Symphony No. 4 'Memorial Candles'
"Brangaene's warning calls were beautifully sung by Kimball Wheeler."
Opera Magazine, June 1990
"Kimball Wheeler sang the solo part of these songs not only with a wondrously beautiful, artfully timbred and modulated voice, but also with great intensity of expression which reached moving moments in the realm of the inner and dreamlike feelings, as well as in the realm of the dramatic and emotional. She possesses a strong power of suggestion which holds her listeners completely enthralled."
