Four months after laying off 53 employees to close a projected $8 million deficit, the California Academy of Sciences is handing its marquee attraction — the 75-foot Morrison Planetarium dome — to a Spotify-produced listening party for Phoebe Bridgers' new album, running August 10 through 14.

To San Francisco Chronicle readers, the event is a novelty: the Morrison is the only Bay Area stop on a 40-plus-venue global campaign for Bridgers' Lost Weekend, staged beneath one of the world's largest all-digital domes. But the Academy's own books reframe it. In an April 28 letter, then-executive director Scott D. Sampson told staff the nonprofit was cutting 9.3% of its workforce because "revenue growth is not keeping up with rising expenses" and singled out investment in "ones that are key for revenue growth" as the survival priority. A corporate music campaign in the dome is precisely that strategy made visible — even as the museum won't say what, if anything, it is being paid.

The California Academy of Sciences is one of the Bay Area's most beloved institutions — a nonprofit that cares for 60,000 live animals and stewards nearly 46 million scientific specimens in Golden Gate Park. It is also broke.

In a letter to staff dated April 28, then-executive director Scott D. Sampson laid out the math plainly. The Academy ran a $7.3 million cash deficit in fiscal 2025, with the current year's shortfall "projected to exceed $8.0 million." To close the gap, management laid off 53 staff — roughly 9.3% of the team — including 37 union-represented workers and 16 non-union employees. Another 32 positions were reassigned or had hours cut. "Reducing staff is always a last resort," Sampson wrote. "Our dedicated staff members are the lifeblood of the Academy."

It was, by the letter's own account, the museum's second round of cuts since 2020 — "two cycles of reductions and re-growth," Sampson wrote, blaming a collapse in San Francisco tourism, shifting post-pandemic audience habits, and federal funding cuts that have intensified competition for philanthropy. The leadership churn hasn't stopped: the Academy has since announced Sampson is stepping down after nearly seven years, with Amber Mace named interim executive director.

Against that backdrop arrives Phoebe Bridgers. Starting Monday, the Morrison Planetarium hosts a full-album playback of Lost Weekend — Bridgers' first solo record in six years, out August 14 on Dead Oceans — paired with a dome film or laser visuals, according to the San Francisco Chronicle. The rollout is produced in partnership with Spotify; Bridgers is not expected to attend the San Francisco sessions. The Morrison is the campaign's only Bay Area date, part of a series spanning more than 40 venues worldwide between August 10 and 14, Pollstar reported. (Lost Weekend is real and well-reviewed — The Guardian called the return "a thrilling, daring study in dislocation.")

Here is what the Academy has not said: how much money, if any, the Bridgers campaign brings in. As of this week, the event does not appear on the Academy's public calendar, which lists its current planetarium programming as a family show tied to the "Tiny Chef" character. Chronicle reporting notes that San Francisco showtimes and ticket prices had not been announced — leaving the ticketing model, and the Academy's cut, unclear.

That silence matters because the layoff letter itself points at commercial revenue as the way out. The Senior Leadership Team, Sampson wrote, made cuts "with a focus on prioritizing our visitor experience, education, and scientific research even as we need to reduce certain parts of our operations… especially ones that are key for revenue growth and longer-term organizational stability." Salaries and benefits, the letter notes, are about 70% of the operating budget; roughly half of earned revenue comes from visitors, members, and sales.

Renting a globally recognized dome to a streaming giant is a rational move for an institution bleeding cash — arguably exactly the "revenue growth" the letter promised to chase. But it also sharpens an uncomfortable question for the workers who were shown the door in April, and for the union that represented most of them: when a public-serving science nonprofit turns its signature space into a brand activation, who benefits, and by how much? The Academy did not detail the terms. Neither did Spotify. Until they do, the dome will glow for Lost Weekend while the balance sheet stays in the dark.
