Mark Slater’s creative-production practice · est. 2013

Study №1 · a conceptual study

The register: one idea, six possible forms

A choir rehearses in an empty station after the last train.

Choose the form it takes.

Below: the same study in all six of its possible forms.

Arrow keys move between forms; number keys 1 to 6 choose a form directly; 0 or Escape returns to undecided, showing all six documents.

ScreenplayFIRST DRAFT — UNPRODUCED

AFTER THE LAST TRAIN

INT. RAILWAY STATION, CONCOURSE — NIGHT

The departures board has gone blank. A cleaner’s trolley stands abandoned by the barriers.

Somewhere past the ticket hall, a single voice finds a note and holds it. Another joins. Then forty.

The sound climbs into the iron roof and stays.

Film gives the idea duration — a night that must be lived through in order.

After the Last Train

One

The last train left at 23:41, and the station exhaled. It was the low voice that began it — one note set against the hum of the vending machines — and the others came in the way swimmers enter cold water: one by one, gasping, glad.

By midnight the concourse had forgotten it was ever a place for leaving.

A book gives the idea interiority — you are told what the singing is for.

forty voices in an iron sky.

Music gives the idea pulse — it happens again each time it is sung.

Photography gives the idea an instant — one frame that stands for the whole night.

Gallery placardConceptual study — not exhibited

After the Last Train, undated

Sound installation: forty recorded voices, a decommissioned departures board, timetable paper.

Dimensions variable.

Art gives the idea an object — something that goes on standing there without you.

AFTER THE LAST TRAIN — SC. 1, THE CONCOURSE

House hum. The departures board flickers out.

LX Q3 — GO

THE CHOIR enters severally through barrier 4, in coats, as passengers who missed nothing.

CONDUCTOR

(raising a hand, to the roof rather than the singers)

Listen. The building is in E.

The note begins before we see who starts it.

SQ 2 — GO

Theatre gives the idea presence — bodies in the room, and the risk that tonight it goes differently.

Studies №1 and №2 are conceptual — written to show how the practice thinks, not records of produced work. The real record is further down the page.

The practice

The moment before a medium

Crowded Mind is Mark Slater’s creative-production practice, and the name of the company he founded in 2013. It is built around one conviction: an idea arrives before its medium does. For a while, the same fragment could still become a film, a book, a song, a photograph, an artwork or a performance — and each of those futures would keep something the others give up.

Today, Crowded Mind is an umbrella around Mark’s work across composition, writing, visual culture, technology and production. The finished work may live elsewhere; this is the place where its possible forms are held together long enough to choose well.

The six forms are not departments. They are the six notations one practice writes in.

We produce the idea first, and the medium second.

Study №2 · a conceptual study

How an idea crosses

A second study, followed across four crossings. At each border, something is lost and something is found. The margin notes record the exchange.

An orchard is divided between two brothers, tree by tree.

  1. Caption sheetSTUDY — NOT PRINTED

    Frame 7 — Two ladders against one apple tree, leaning from opposite sides. Late light. Nobody in frame.

    Found: the image — two ladders, one tree. Lost: which brother owns it.

  2. Gallery placardConceptual study — not exhibited

    The Inventory, undated. 214 numbered brass tags, one orchard map cut in half. Dimensions variable.

    Found: the count — division made physical. Lost: the season.

  3. ScreenplayFIRST DRAFT — UNPRODUCED

    EXT. ORCHARD — DAWN. Two men walk the rows with paint. Red marks. White marks. Neither speaks. One tree at the boundary is left unmarked.

    Found: time — the unmarked tree can wait until the last scene. Lost: stillness.

  4. Book proofUNCORRECTED — NOT FOR SALE

    Their father had counted the trees every autumn, and so the number 214 was the only will he needed. It did not divide by two. That was the sentence neither brother said aloud.

    Found: the reason. A book can say the unsaid number. Lost: the light.

The idea survives every crossing. The medium is a decision about what to keep.
