Alex Chinneck‘s Bangers and Mash, premiering today at London’s Treasure House Fair, is a life-sized grand pianocarved entirely from American Black Walnut — one of the hardest and most structurally stable domestic timbers in sculptural practice — that has been made to look as though it no longer has any structural integrity at all. A stack of antique 19th-century books presses down on the instrument’s body, sending waves and ripples through the case, the keyboard, and every straight line the piano once had. The two-metre-high carved sculpture does not depict compression as a physical event. It depicts it as a permanent condition, fixed forever in a material that cannot actually bend.
The title is the first contradiction. Bangers and Mash — British working-class slang for sausage and mashed potato — applied to a grand piano being systematically destroyed by a column of 19th-century leather-bound books inside a fair that also features works by Picasso, Dalí, Henry Moore, and David Hockney. The register is deliberate. Chinneck’s practice has always operated at the intersection of the monumental and the absurd, the technically demanding and the visually comic, and the title here does in two words what the sculpture does in three dimensions: it punctures the expected solemnity of the object before the eye has time to supply it.
The material choice is the work’s most precise argument. American Black Walnut is dense, dimensionally stable, and resistant to deformation — it is the timber of choice precisely because it holds its shape. Chinneck and his collaborator Jonathan Fernhead have carved it into a form that reads as the opposite: a body losing its geometry under load, keyboard keys that curve where they should be flat, a case that ripples where it should be rigid. The vintage Bakelite piano keys embedded in the carved walnut body extend the anachronism further — Bakelite, an early synthetic plastic prized for its hardness and heat resistance, here occupying a form that implies softness and failure.
The books are not a metaphor Chinneck has left open. They press down with the visual logic of actual weight — spines visible, stacked with the particular authority of 19th-century volumes — and the piano responds as though the weight were real and ongoing. The waves and ripples travel through the instrument’s form in the manner of slow deformation, as though the process is still happening and simply caught at a particular moment. This is a recurring strategy in Chinneck’s large-scale public sculpture: the arrested moment, the impossible material state presented as documentary evidence of something that could not have occurred. As he has demonstrated across his career — from facades peeling away from buildings to brick walls dissolving mid-collapse — the work is always most effective when the viewer’s eye accepts what the mind knows to be structurally impossible.
The context of the Treasure House Fair adds a layer the studio has not foregrounded. The fair, held in the historic grounds of the Royal Hospital Chelsea and now in its fourth year, brings together galleries dealing in antiques and works by canonical twentieth-century figures. The Sculpture Walk — within which Bangers and Mash appears — was curated by sculpture specialist Flo Horswell, art historian Wilfrid Wright, and New York-based interior designer Benjamin Brougham, and includes 35 works throughout the fair. Placing a squashed walnut piano in this context is not an accident of logistics. The 19th-century books that destroy the instrument are drawn from the same period as the antiques surrounding it. The fair’s inventory and Chinneck’s sculptural material are from the same historical moment — one preserved, the other weaponized.
Robert Young Antiques, the exhibitor who invited Chinneck to show at the fair’s Sculpture Walk, has long engaged with the artist’s practice. Robert Young said “Alex’s work challenges perceptions, explores mediums, pushes boundaries and defies gravity, whilst also going some way to redefining the understanding of contemporary sculpture.” The pairing of a folk art specialist with a sculptor whose primary subject is material impossibility is itself a form of cross-disciplinary logic — the same instinct that runs through the work itself, which treats the antique piano and the antique book as objects belonging to the same cultural register, then stages their collision.
Chinneck’s own framing of the collaboration is characteristically precise about process rather than product. “I have always enjoyed forging working partnerships in places you wouldn’t typically expect to find contemporary artists,”he said. “Cross-interest, cross-sector and cross-disciplinary collaborations give birth to surprising outcomes.” The statement applies equally to the sculpture’s own internal logic: the cross between furniture and instrument, between collapse and permanence, between a title that suggests the kitchen table and a material that suggests the concert hall. The photographs by Charles Emerson, shot at The Astor Theatre in Deal against deep red stage curtains, frame the sculpture as something between an abandoned prop and a stage presence — the theatre setting adding a performative register to an object that is, after all, built around the idea of a performance that can no longer take place.
The Dior window sculptures Chinneck produced for New York and Beverly Hills earlier this year operated on a related principle — objects familiar enough to read instantly, made strange through a single material intervention that the viewer cannot immediately explain. Bangers and Mash applies the same method at a different scale and in a different institutional context, but the core question is unchanged: what happens to an object’s meaning when its physical logic is overturned while its material remains?
The most precise thing Bangers and Mash does is refuse to choose between funny and serious — and that refusal is harder to sustain in carved walnut than it looks. Sculpture that operates at the level of visual comedy risks dissolving into illustration the moment the joke lands; sculpture that operates at the level of material investigation risks becoming inert the moment the concept is understood. Chinneck’s work at its strongest holds both registers simultaneously, long enough that the viewer keeps looking after the punchline has already arrived. Whether a squashed piano in American Black Walnut at an antiques fair in Chelsea can hold that tension for the full six days of the fair is the only question the press release cannot answer.
