The piquant Jeremy Denk set himself a challenge in his recital at the University of Hong Kong by presenting an ambitious programme of solo piano works that explored the notion of profundity and whether it exists in music. His choice of pieces for his Hong Kong debut was notable for the fact they were written late in each composer’s life and at a time of personal foreboding. However, while all of them show degrees of structural audacity and adventurous tonal exploration, in or of themselves none can conclusively be deemed profound. The American is a soundscapist, capable of communicating an understanding of the music at every turn. Prokofiev’s Visions Fugitives allowed him to show off that ability , as he seesawed between a finely weighted touch and bold dramatic execution. François-Frédéric Guy Plays Beethoven review: bold musical choices and a few shaky moments Denk approached Mozart’s famous Rondo in A Minor, K511, in a rather leisurely manner, but produced extremes of dynamic contrast and tempo variation. This was a romanticised reading, with particularly noticeable pauses included after cadence points. Conducting with his other hand when a single hand was playing, as another American pianist, Glenn Gould, famously did, Denk sought to emphasise significant compositional moments both musically and physically. Piercing glances directed at the audience ensured we understood his intent. To make sure we were with him on the journey, Denk returned with microphone in hand, perhaps with the intention of rationalising his 19th-century stylisation of the Mozart. He mentioned the notion of time and how Mozart and Beethoven approached it differently. This he demonstrated in the third work of the evening, Beethoven’s Piano Sonata No. 30 in E Minor, Opus 109, playing the opening of its third movement as though time had stood still. This approach to the hymnlike material was ethereal, and its return, after a turbulent, trill-laden passage, was transcendent. Denk’s last-minute inclusion of Schubert’s Sonata No. 21 in B-flat Major, D960, in place of the Liszt and Schumann works advertised, was astute. Although no explanation was offered for the switch, Denk’s rendering of the work gave him the opportunity to exploit the work’s episodes of darkness and light. Instead of the usual showmanship of solo piano recitals, this was a programme that offered a pathway to the sublime. In the first of two encores, Denk revisited Mozart; the second, Donald Lambert’s ragtime version of Wagner’s Pilgrim’s Chorus, seemed out of place in an evening dedicated to exploring profundity. Indeed, the pianist admitted as much, excusing it as “something silly”. Notes of Profundity: Jeremy Denk in Recital, University of Hong Kong. Reviewed: June 1, 8pm
