"Things I Wasn't Able to Tell You" by Berlin-based composer and pianist Nunu Kiefer or just nunu is an album that invites listeners into an intimate soundscape where each note seems to carry the weight of unspoken words and the poignancy of unsent letters. The album, a fusion of modern classical and so-called new impressionist pianism, showcases nunu's deftness at the piano, her compositions resembling diary entries more than conventional tracks. This personal touch is evident as she delicately balances minimalistic piano melodies with subtle electronic undercurrents provided by collaborator Kopfkino on a couple of tracks ("Yesterdays" and "In Between").

From the first note of "Yesterdays", nunu's touch on the piano is both gentle and assertive, much like a painter sketching memories onto a canvas. Her style is characterized by a tranquil atmosphere that at times bursts into bright, emotional colors. The pieces feel like fleeting moments captured in sound, expressing a range of emotions from nostalgia in "After Seven Years" to the melancholic beauty of "The Fairy".

Technically, the album is a masterclass in restraint and expression. The piano lines are clean and precise, yet imbued with a warmth that suggests a deeply personal connection to the music. The electronic elements, while never overpowering, add layers of texture and depth, creating a sonic landscape that is both expansive and intimate. The production quality, overseen by Hiroshi Iguchi, ensures that each note is crisp and clear, allowing the emotional resonance of nunu's compositions to shine through.

In a market flooded with overproduced electronic music and flashy piano solos, nunu's "Things I Wasn't Able to Tell You" stands out as a beacon of sincerity and artistic integrity. It is an album that not only showcases nunu's technical prowess but also her ability to convey profound emotion through music. Each track is a page from her life's diary, filled with stories and sentiments that words alone could never capture. This makes the album not just a collection of songs, but a heartfelt communication of what it means to be human.
