Krystian Zimerman, a renowned Polish pianist, performed in Luxembourg in a concert that featured a wide range of classical music, from works by Beethoven and Schubert to a selection of preludes and other pieces spanning from Bach to Gershwin. The concert program was announced in the late afternoon, underscoring Zimerman's status as a leading figure in the classical music world. The event took place in a full concert hall, where the audience was clearly engaged and appreciative of the performance. Zimerman's interpretation of Beethoven's Sonata No. 21 "Waldstein" stood out for its use of a muted piano, particularly in the lower register. However, the acoustics of the Philharmonie de Luxembourg allowed this choice to resonate fully. The first movement showcased the full range of the piano's capabilities, while the finale was performed at a restrained tempo, emphasizing poetic expression and contrasting with faster sections. This approach gave the piece a reflective and nuanced quality. In his performance of Schubert's Impromptus D. 899, Zimerman offered a clear and less unsettling interpretation compared to his previous renditions. The second half of the concert featured a program titled "Fragments of preludes and others," which included eight groups of two pieces, each pairing a major key with its relative minor. The repertoire spanned a variety of composers, including Bach, Chopin, Rachmaninov, Roman Statkowski, Nikolai Kapustin, Debussy, Franck, and Fauré. While the program was intriguing in its structure, some questioned the relevance of the approach, especially the inspiration behind the selection of pieces. Zimerman's performance of Chopin's works demonstrated a deep connection to the composer without veering into sentimentality. There was a sense that more of Bach's luminous and airy style would have been appreciated. The concert concluded without any encores, leaving the audience with a thoughtful and reflective experience.
