The lockbox is still bolted to the stair railing outside the Hancock Street brownstone. Steven Rosenthal came by Friday to look at it. He is the man who recorded David Bowie's last album. His daughter Tracy is the woman the Mayor's office wants you to see as the face of tenant power in New York.

The Magic Shop, the SoHo studio he founded in 1988, recorded Coldplay's "Viva la Vida," which sold more than ten million copies, the Foo Fighters' "Sonic Highways," and Bowie's "Blackstar." Tracy grew up with that access. She attended the Grammys with her father at least twice, in 2011 and 2023, and grew up in a NoMad apartment the New York Post values at $1.7 million. She has posed for a photograph on Karl Marx's grave in London.

On August 4, the Mayor's office released a documentary about tenant organizing. Rosenthal appears in it. The same week, Mamdani signed a "Right to Organize" letter reminding renters they can knock on their neighbors' doors and form associations. Those are Rosenthal's tactics, laid out in her 2024 book "Abolish Rent." The city adopted the playbook and put its author on camera.

Here is what the author did with the playbook. She moved into a two-bedroom top-floor apartment in Bed-Stuy at $2,300 a month, found roaches, and organized the building's tenants to stop paying rent. She has withheld payment for four years and stiffed the owner of at least $108,000 on her unit alone. "We've been on rent strike ever since," she told a North Carolina DSA meeting last August, and she said it proudly.

The city adopted the playbook, then put its author on camera and called her a hero.

The building went to foreclosure in 2023. US Bank, the new owner, filed in housing court in November to evict Rosenthal and four other tenants, saying they "squatted upon the premises." The cases are still open. And the building that houses the rent strike is not a slum. Earlier this year the Housing Preservation Department placed it in the Alternative Enforcement Program. It came off the program on July 14 after the issues were resolved, according to a city notice taped to the front door this week.

That program is the machinery. A previous Post analysis found it is the same mechanism the administration wants to use to seize housing, and it received a $2 billion budget boost. A housing court judge can appoint a nonprofit to take over a building's management. The tenant strategist withholds the rent, the building enters the enforcement pipeline, the city stands ready to reassign the deed. Each piece was built separately. They fit together. It is the same move as the rent freeze, where Mamdani did not abolish the Rent Guidelines Board, he simply filled six of nine seats and let the board's own procedural legitimacy launder a campaign promise into policy.

The documentary itself is built on one such case. Rosenthal worked as a strategist for tenants across 93 buildings owned by the Pinnacle Group, helped them form a union, and the union secured repairs and millions in forgiven back rent after the bankrupt landlord sold its 5,200-unit portfolio. That fight is the subject of the film the Mayor's office paid for. The office that paid for it is not a metaphor. It is the $53 million Office of Mass Engagement, the DSA field operation Mamdani moved onto the city payroll, and canvassing for the rent agenda is its documented product.

Stu Smith, the City Journal investigative analyst who has been studying the rent abolitionist movement, put the point plainly when his piece ran.

Smith read the ideology out of Rosenthal's own manifesto. "Abolish Rent," co-authored with Leonardo Vilchis, argues that tenants should become "the architects of a long-term project of expropriation." It appears on a DSA recommendations list and anchors the DSA's Nationwide Abolish Rent Reading Group. The escalation ladder Smith documents runs from demands to rent strikes to directly targeting landlords: camping on their lawns, bad reviews of their other businesses, disrupting private gatherings. Rosenthal and her allies once crashed a landlord's daughter's wedding as a "social sanction." She later called it "really fun."

Smith also maps the tie the Post photo only hints at. Rosenthal is close with Cea Weaver, Mamdani's appointed tenant advocate and a key campaign advisor. Teen Vogue framed the pair as tenant leaders in 2020. By 2026 they were fixtures of the same conference circuit, Weaver facilitating panels featuring Rosenthal. Weaver's stated premise, quoted by Smith: "the power relationships between tenants and landlords, period, are bad." That is the through-line Smith draws himself: the movement quoted at a People's Forum panel is no longer on the outside. It advises the mayor.

Smith's piece carries the part the celebration leaves out. He documents three New York cases where the landlord ended up dead: Zoraida Leo, strangled in 2023 in a dispute over rent; superintendent Jose Portillo, killed in January 2025 while allegedly trying to collect $24,000 in arrears; and 99-year-old Jose Antonio Tur, attacked by a former tenant who allegedly owed him more than $30,000, dead of a stroke the day after. A movement that frames paying rent as done "at the barrel of a gun," Smith argues, is a movement that has told you how it sees the other side of the lease.

This is the administration's recurring move: confer official legitimacy on people whose defining act is celebrating the thing the law is supposed to prevent. It credentialed Luigi Mangione's cheerleaders as press. It froze the rent by changing the referee. Now it hands a documentary and a "hero" frame to a strategist who owes $108,000 and is being sued for eviction. The methods are the message.

Steven Rosenthal knows the other side of this. The Magic Shop closed in 2016 after a dispute with its landlord. He tried to buy the space, backed financially by Dave Grohl, and the co-op board rejected the bid. The father lost a room full of history to a landlord and a board. The daughter turned losing a landlord into a career.

The lockbox is still on the railing. The rent is still unpaid. The eviction case is still in court. And the city that could resolve any of it instead made a movie about the woman who owes the money.
