Beethoven's "Hammerklavier" Sonata:
"Mr. Howard is not only a virtuoso of the first order but a deeply serious musician whose sense of structure served him to the greatest advantage in the sonata. The scale of the first movement was immense, with no trace of hardness in the tone. The Scherzo, taken fast, was for once perfectly accentuated while the great slow movement emerged as the ultimate fulfilment of the composer's art. The fugue was breathtaking in its intensity and clarity."
The Daily Telegraph

Schumann's Fantasy:
"A performance which gave a magical impression of inspired improvisation, culminating in one of the most elegiac finales I have ever heard."

Rakhmaninov's Sonata no. 2 [original version]:
" A truly diabolical sweep and panache in a reading both structurally coherent and virtuosically exciting. After such a performance, a Chicago Symphony engagement would be warranted."
John von Rhein - Chicago Tribune

Bryce Morrison
“Howard always seems to know where the music is going and why.”
Gramophone

"Howard is, by general consensus, the finest living exponent of Liszt, and his traversals afford all-enveloping verve and charisma, tremendous daring
and a formidable intellectual grasp of the music...his vastly superior performances will continue to carry the day."
