“…it was obvious at once that Deborah’s Wagner credentials were for real: a fine Wagner voice, large enough to cope with the orchestra surrounding her and the acoustic (of St Paul’s Cathedral)…beautiful and fully expressive of the sense of the words…these were the characteristics of Humble’s performance; beautifully phrased, warm and rounded in the lower register, lustrous and spiritual as her lines went high into the soprano range. She invested the songs with a dramatic quality that could be heard as the product of a totally theatrical performer.” (Wesendonck Lieder, Orchestra Wellington, Lindis Taylor, Classical Music Review, May 2014)

“From the opening of the recital Humble immediately established herself  as a most accomplished exponent of Lieder. Her rich, full tone is evenly produced throughout the range and her warm vocal production is achieved without intrusive vibrato. At the height of emotionally charged phrases her voice filled the hall effortlessly. She quickly established a close rapport with her audience  and seemed to draw her listeners into the emotional world of whatever song she was currently singing. Like all accomplished Lieder singers Humble pays close attention to the text and clearly communicates its changing moods to the audience.  In Wagner’s ‘Wesendonck Lieder’ Humble excelled with her effortlessly full tone and her long, soaring sostenuto phrases. Her close communication with the audience created an intensely poignant atmosphere, particularly in the last song ‘Traume.’  In general, Humble’s infectious personality completely won over the audience with her engagingly seductive performance.”  (Solo Recital, Great Australian Wagnerians in Concert, Verbrugghen Hall, Sydney, Larry Turner, Sounds Like Sydney, June 2014)

“Apart from possessing a beautiful voice, with riveting dark hued notes and an absolutely secure technique throughout her impressive vocal range, Humble’s gifts as a storyteller are remarkable. This could perhaps be attributed to her extensive experience on the operatic stage, but seems rather to stem from an innate ability to inhabit the spirit of a song and bring its characters and characteristics into sharp focus…there is a genuine warmth and sweetness that charmed the audience into entering the microcosms of Brahm’s and Wagner’s creations.’Immer Leise wird mein Schlummer’ was a study in the power of word painting and the soft, gentle singing of ‘Wie Melodien sieht es mir’ was simply ravishing. In the ‘Wesendonck Lieder’ Humble displayed rhythmic elasticity, dramatic urgency, colour, line and top notes that bloomed effortlessly, resulting in a very special musical experience. Going by the enthusiastic reception that greeted her alluring performance, it would be fair to say that every member of the audience was thoroughly seduced.”  (Solo Recital, Melbourne, Heather Leviston, Classic Melbourne, June 2014 )

Her singing makes you forget where you are.” (Messiah, Royal Melbourne Philharmonic, Morag Fraser, Australian Book Review, December 2014)

“Elegant in a black, sleeveless gown, Humble edged Bluebeard’s fourth wife Judith with strident complexity and magnetic gesticulation. Exhibiting luscious, cavernous dark tones and lucent, gleaming highs, she slithered across the vocals with both dramatic and lyric force, culminating in a piercingly ecstatic display of strength and exuberance as Bluebeard’s vast kingdom is revealed behind the fifth door in a staging highlight. Humble’s manipulative and momentary manic portrayal of Judith’s obsession to learn the truth made a convincing picture of a woman on a mission to redeem the malevolent Bluebeard.” (Bluebeard’s Castle, Monash Academy Orchestra, Paul Selar, aussietheatre, August 2015)

“The part of Judith calls for a mezzo-soprano with power throughout a wide range and Humble has just that. She is also blessed with an expressive, steady voice of unfailing beauty.

“Deborah Humble sang the Brahms (Opus 91) beautifully, giving a sense of the depth of emotion within the text.

She evoked the deep emotion beautifully, showing off every quality of her voice from a powerful darkness to a soft, floating transcendence.” (Solo recital, Sydney, Deen Hamaker, Sounds Like Sydney, October 2016)

“Looking a little like Mathilde Wesendonck herself, Ms Humble sang these musical heart-throbs  (Wesendonck Lieder) magnificently, and got a well-deserved, rousing reception from a large and enthusiastic crowd.” (Solo Recital, Adelaide, Wagner Newsletter, February 2017)

Deborah Humble, one of the best opera singers to emerge from Adelaide in recent times, effortlessly filled the spacious interior of St John’s Church with her magnificently resonant voice. Wagner’s Wesendonck Lieder really took flight. Deborah’s voice, as rich and dark as a great Australian Shiraz, reached into the emotional depths of this music in a commanding and totally engrossing manner.” (Solo Recital, Adelaide, Stephen Whittington, The Advertiser, February 2017)

Deborah Humble had a beautiful, smoothly produced mezzo, rather showing up the veteran singers who are so often cast in this role.” (Klytamnestra, Edinburgh Opera, Opera Scotland review, October 2017)
