Some composers write for the piano. Helmut Lachenmann writes against it, around it, sometimes seemingly despite it. This Thanatosis release, arriving neatly for his 90th birthday, finally gathers the complete solo piano works into a single object, and what emerges is less a corpus than a long, stubborn argument with an instrument that keeps refusing to behave.
Jonas Olsson is the right person to mediate this dispute. He has worked closely with Lachenmann, knows the difference between a note and a residue, and understands that in this music sound is often a side-effect rather than the goal. The piano here is not a noble Romantic beast but a physical system: keys scraped, strings touched, pedals half-engaged, resonance treated as material rather than decoration. Olsson doesn’t dramatize this. He simply lets the actions speak, which is harder and more convincing.
The early "5 Variationen über ein Thema von Franz Schubert" already feel like a polite door being closed. Schubert’s dance is present, yes, but constantly interrupted, irritated, eroded. It’s tradition viewed through clenched teeth. By "Echo Andante", the piano has learned a new trick: to exist mainly as an afterimage. Attacks matter less than what lingers, and the real composition seems to happen in the air after the hands have already moved on. It’s severe, but oddly tender, like someone whispering to a room and trusting it to remember.
"Wiegenmusik" and "Guero" sharpen this attitude. The former rocks uneasily, never quite settling into comfort, while the latter famously turns the piano into a percussion instrument that forgot it was supposed to sing. Fingernails, wood, friction, breathless quiet. Anyone expecting virtuosity in the usual sense should recalibrate. The difficulty here is not speed or volume, but restraint and nerve.
The cycle "Ein Kinderspiel" is where Lachenmann’s reputation for austerity quietly cracks. Written for his son, these miniature pieces are approachable without being simple, playful without being naive. Nursery tunes are filtered, distorted, placed at the edges of the keyboard, where sound thins out and resonance becomes the real protagonist. It’s music that remembers childhood without romanticizing it, which is rarer than it should be.
At the center sits "Serynade", a sprawling, unbroken work that feels like the piano discovering its own internal weather system. Resonance piles on resonance, sections bleed into each other, and moments of brilliance collapse into noise or silence without warning. Olsson navigates this with an impressive sense of long form. He doesn’t smooth the rough edges, but he makes the arc clear, letting tension accumulate and release with a logic that only becomes apparent in retrospect.
The final pieces, "Berliner Kirschblüten" and "Marche fatale", arrive late in Lachenmann’s life and sound like a grim smile. The piano no longer argues; it mutters, laughs darkly, stumbles forward. There is bitterness here, but also a refusal to turn reflective or nostalgic. Even at the end, Lachenmann avoids the comfort of summing up.
The production, recorded at Norrlandsoperan, captures the essential fragility of these works: the way silence presses in, the way tiny sounds suddenly matter. The booklet, with diagrams, notes by Paul Griffiths, and a long interview conducted by Olsson himself, reinforces the sense that this is not just a performance but a document.
This CD won’t convert skeptics overnight, and it doesn’t try to. What it offers instead is clarity: a full view of how one composer spent seven decades asking what sound is allowed to be. With Olsson’s focused, unsentimental playing, these pieces don’t feel like museum objects or academic exercises. They feel alive, awkward, sometimes funny in a dry, sideways way, and stubbornly human. For Lachenmann’s piano music, this is very likely the reference recording. And for the piano itself, it’s another reminder that survival sometimes means learning to make noise differently.
