“The Bacewicz String Quartet’s recording of Paul Kletzki’s complete string quartets is a remarkable achievement, both technically and artistically. The soundstage is wide and deep, with each instrument clearly defined yet perfectly balanced, creating a unified ensemble tone without any part feeling artificially spotlighted. The violins are soft and never harsh, dynamics are broad and well-controlled, and even micro-details—the slightest bowing nuances or subtle mechanical noises—are rendered naturally, contributing to realism without self-indulgence. The performances themselves are emotionally compelling, conveying tension, lyricism, and inner intensity with apparent ease. Altogether, Prelude Classics has produced an album that feels fresh and alive, allowing listeners to immerse themselves fully in Kletzki’s music while appreciating the clarity, depth, and warmth of the recording.” - Matteo Bruni

“The recording by Manufaktura Prelude Classics, made in DXD format (352.8 kHz / 24-bit), stands out for its reference-quality sound. It offers remarkable clarity, a deep and naturally shaped soundstage, and the tonal richness of the instruments, allowing the nuances of the quartet’s performance to be fully appreciated. The album Hidden Voices is an exceptional recording that not only documents Kletzki’s forgotten string quartets but also fully restores their significance in the history of 20th-century music.” - Jean-Jacques Millo

“The Bacewicz String Quartet delivers technically flawless and passionately expressive performances that bring Kletzki’s long-forgotten quartets vividly to life. The recording itself, engineered by violinist Michal Bryla, is superb in every respect—perfectly balanced, completely transparent, yet sonorous and warm—making it a truly outstanding contribution to this remarkable homage to the composer.” - Aart van der Wal

“The album Paul Kletzki: The Complete String Quartets, performed by the Bacewicz String Quartet, is a remarkable achievement that brings Kletzki’s forgotten quartets vividly to life. The quartet’s playing is characterized by clear structure, precise articulation, and sensitive phrasing, revealing the rich rhetoric of the music without oversimplification. The recording, produced by Michał Bryła for Prelude Classics, is exceptional—offering intimate perspective, deep and well-defined soundstage, full, vibrant tones from viola and cello, and a perfectly captured “breath” of the violins. Every micro-detail, from bow noise to room resonance, serves the music’s transparency and expressive logic, resulting in an extraordinary listening experience that combines analytical clarity with emotional immediacy.” - Robert Majewski
