Nightlife is urban memory.

Most nightlife history survives in fragments: a flyer in a drawer, a story told at 4 AM, a track ID nobody wrote down, a room that became condos. AFTR/IMG gathers those fragments into a navigable public memory.

Nightlife is where music scenes incubate, where queer and immigrant communities build space for themselves, and where a city's architecture gets a second, nocturnal life. It is also one of the least-archived parts of urban culture — rarely documented while it is happening, and easily erased once it is gone.

A list of venues is a database. A map is an argument. Plotting nightlife on real coordinates makes patterns legible: how a sound travelled a few blocks from one room to the next, how scenes clustered along a transit line or an industrial waterfront, how a neighborhood's character changed as its rooms opened and closed.

Time is treated as a primary dimension alongside space. Filtering the atlas by decade is not a convenience — it is the point. You should be able to watch the city's nightlife geography shift era by era.

New York is where much of modern dance music culture was assembled — the loft party, the members-only club, the garage and house continuum, ballroom, and the downtown art-and-noise scenes — and it is a city that has repeatedly demolished or converted the rooms where that history happened.

Starting in one dense, well-documented city lets AFTR/IMG build a careful methodology before expanding: how to source claims, how to represent uncertainty, and how to invite correction from the people who were actually there.

This is a prototype seeded with starter records. Where AFTR/IMG does not yet hold citations, the copy says so — using language like “associated with,” “remembered for,” and “often cited within.” Coordinates for several rooms are approximate. Nothing here should be read as settled history; every record is a starting point meant to be corrected and sourced over time.

Future versions will add verified citations and contributor attribution, archival uploads for flyers, photos, and audio, recorded oral histories, and connections between people, parties, and sound systems — not only venues. The data model is already designed to move from local seed files to a hosted database without rework.

After New York, the same methodology can extend to other cities, each mapped on its own terms.

Because an archive built from fragments has to be honest about what it holds, AFTR/IMG marks confidence directly on every record, with four states:

• Verified — dates and core facts corroborated against a source.
• Needs review — plausible starter data, awaiting corroboration.
• Approximate — a span or coordinate is deliberately rough (after-hours and roving parties often have no fixed pin).
• Disputed — conflicting accounts on record.

Quotes and oral histories appear only when they can be attributed; until then, the slot is left visibly empty rather than filled with something invented. People who have rebranded are recorded under their current name with former names preserved. The underlying data model — venues, figures, parties, oral histories, and confidence flags — is built to move from local seed files to a hosted database without rework.
