Starter Service Kit

A concrete product with a clear subject and real-world context.

This page frames a concrete subject instead of using a generic heading. It explains what is being considered, why it matters in the site's context, and what detail a reader can expect next. The copy is intentionally plain and specific, so it reads like a real content item.

Guided Setup Option

A focused product built around practical decisions and constraints.

This item focuses on practical use, tradeoffs, and decisions that a reader may recognize. It avoids broad promotional claims and keeps the topic tied to a clear situation. The description gives enough substance for a real page rather than a placeholder card.

Ongoing Support Package

A grounded product that adds a different angle without repeating the others.

This page gives the third item its own reason to exist. It covers a separate angle, includes concrete context, and avoids repeating the same promise in different words. The result should feel like a planned article, project, review, or offer.

Notes from collectors, programmers & engineers

What the people who dig through the crates say about the catalog.

“The liner notes are the real deal — session dates, gear lists, even the room mics. You can tell this was put together by people who actually listen.”
DM

Dana M.

Radio programmer, KXCI

“I’ve pulled three tracks for sync placements straight from the demo sessions. The contact info is right there, and the press kits are actually useful.”
JT

J. Torres

Music supervisor, indie film

“The background stories on recording locations are a goldmine. It’s not just a catalog — it’s a map of where the underground actually lives.”

Archive FAQ

Catalog & licensing questions

How do I request a digital review copy of a release?

Send a short note to our licensing desk at info@fillinrecords.com with the catalog number or artist name. We usually respond within two business days. Review copies are provided as private streaming links or high-res downloads, depending on the format you prefer.

What information is included in each catalog entry?

Every entry lists the original release date, recording location, session credits, and the equipment used during tracking. You'll also find background notes on the production techniques and the story behind the session. For most titles, we include a downloadable press kit with liner notes and hi-res artwork.

Can I license a track for a film, podcast, or playlist?

Yes. We handle sync licensing directly for most of the catalog. Tell us about the project, the cue sheet, and the territory you need. We'll confirm availability and send a licensing agreement with clear terms. Our turnaround for sync requests is usually under a week.

How do I submit my own master recordings for consideration?

We accept demo submissions from independent artists and labels. Send a streaming link (not a download) to info@fillinrecords.com with a short bio and the recording location. We listen to everything, but due to volume we only reply to projects we think fit the archive's sound. Please allow 3–4 weeks for a response.

Are the original session tapes or vinyl pressings available?

For a handful of titles, we hold limited vinyl pressings and original tape transfers. These are noted individually on the release page. If you're a collector or radio station looking for a physical copy, reach out and we'll let you know what's currently in stock.

Do you provide detailed liner notes for radio or research use?

Absolutely. Each catalog page includes a full liner notes section with session dates, musicians, and the recording chain. For radio programmers or academic use, we can send a PDF with extended credits and technical notes. Just email us with the catalog ID and your deadline.
