Thousands of Illegal Concert Tapes Recorded Over 40 Years Are Now Available for Free, and Artists Keep Endorsing Them

The collector says if he doesn’t release them now, decades of music and historic performances will disappear forever.

More than 40 years after Aadam Jacobs started sneaking a recorder into Chicago clubs, the archive he built is finally surfacing in public. It holds more than 10,000 shows, more than 3,000 artists, and roughly 40,000 full sets recorded across the city’s underground music scene from 1984 through the 2010s.

Now, volunteers are racing to digitize the tapes before age destroys them, running 10 repaired cassette decks at once while Jacobs keeps mailing in more.

But the scale is almost absurd and the time is quickly running out.

What’s Actually on the Tapes

Across more than 10,000 shows, more than 3,000 artists, and roughly 40,000 full sets, Aadam Jacobs documented Chicago’s live underground from 1984 through the 2010s.

The archive moves across indie rock, punk, post-punk, alt-rock, noise, hip-hop, jam, new wave, and Americana, with roughly 2,500 recordings already online in the Aadam Jacobs Collection and thousands more still waiting behind the transfer backlog.

Some of the most revealing recordings are the ones that capture major artists before their history had fully settled into place.

One of the clearest examples of this is Nirvana’s Chicago debut, recorded at Dreamerz on July 8, 1989, more than two years before Nevermind.

The tape preserves Kurt Cobain greeting the room with the line reported by CBS Chicago as “Hello, we’re Nirvana. We’re from Seattle,” and it captures the full set on a compact Sony cassette recorder Jacobs carried in his pocket.

Years later, Jacobs summed it up with dry honesty: “OK. They weren’t great.”

Other recordings worth hearing

The archive’s value comes through even more clearly once it moves beyond a single marquee name, though. It also includes recordings like:

• Phish at Lounge Ax, recorded on November 9, 1990, opening for Alex Chilton in a performance that had not previously circulated
• Depeche Mode at the Aragon Ballroom, taped on March 22, 1985, and described on its archive page as the only audience recording known to circulate from that date
• R.E.M. at Circle Pavilion UIC, from 1987, including a live “I Believe”
• the Bangles at Cabaret Metro, recorded in October 1984 across a 20-song set
• Godspeed You! Black Emperor at Schubas Tavern, taped in 1998 in a room small enough to make the recording feel especially improbable

Beyond those, the collection also holds Liz Phair at Lounge Ax in 1999, a 1988 Boogie Down Productions recording, and sets by Fugazi, Hüsker Dü, Sonic Youth, the Cure, Björk, Neko Case, Dinosaur Jr., Fred Armisen, and James Brown.

In short, the archive reads less like one collector’s stash than a week-by-week record of how Chicago’s clubs once sounded.

In fact, many of the venues tied to those nights, including Dreamerz, Lounge Ax, Metro, Schubas, Aragon, and Circle Pavilion UIC, have since closed, changed, or slipped into local memory.

So in some cases, these tapes may be the closest thing left to an original record.

Saving the Tapes, One Deck at a Time

Much of the rescue effort runs through Brian Emerick, the lead archivist working from the Chicago suburbs. He transfers tapes on 10 working cassette decks at once, which is a setup that sounds efficient until the math kicks in.

A 90-minute show still takes 90 minutes to digitize, so the only real way to move faster is to keep more machines running at the same time.

But keeping those decks running is part of the job. Many of the machines he finds are broken or half-dead, and because no one makes them anymore, he has had to learn how to repair them himself before they can be put back into service.

After a tape comes off the deck, the work stays manual. For instance, one documented chain, drawn from the Depeche Mode 1985 item page, runs from a Yamaha K-340 deck into a Tascam DR-40 recorder, then into WAV, Audition, Fission, xACT, and finally FLAC.

Fortunately, there are other volunteers that handle the slower work that follows transfer.

One of them is Neil deMause from Brooklyn, who helps with cleanup and metadata, while contributors including kliked, RyanJ, and Avery/vanark appear on archive pages across the collection.

And when a little-known act has no published setlist, volunteers sometimes track down the original musicians to identify the songs.

Even so, the pipeline remains backed up. Emerick has transferred more than 5,500 tapes since late 2024, while only about 2,500 recordings are publicly live. Cleanup, tagging, and verification account for much of the gap.

The Tapes Are Losing

The backlog would have been manageable if the tapes could wait. But they can’t.

While volunteers clean, tag, and verify one batch, other cassettes are already beginning to lose the audio stored on them. Binder breakdown loosens the magnetic coating, oxide builds up on playback heads, and songs can begin dropping out in the middle with no way to restore what was lost.

A transferred recording of R.E.M. at Circle Pavilion UIC in 1987, for example, carries three songs with dropouts that the archivist noted as pre-existing artifacts from the original tape, not problems introduced during digitization. Those gaps are permanent.

That deterioration is what finally pushed Jacobs to release the archive after keeping it close for four decades.

Then, attention helped bring the collection into view. Chicago filmmaker Katlin Schneider’s 2023 documentary Melomaniac put him on more people’s radar, and an Internet Archive volunteer reached out soon after.

Still, Jacobs made clear in Fortune that the real trigger was physical decline.

“Before all the tapes started not working because of time, just disintegrating, I finally said yes,” he shared.

But even with the transfer effort underway, the archive is still arriving faster than it can be processed.

Jacobs sends Brian Emerick between 10 and 20 boxes a month, with Euronews reporting that each box can hold 50 to 100 tapes. At the upper end, that works out to as many as 2,000 new cassettes arriving every 30 days while the transfer decks still run in real time.

In this case, Emerick has said the project will take years to catch up with what is already in hand.

Every Recording Is Technically Illegal

The archive exists in a legal gray area, even if almost no one involved seems eager to test it in court.

In theory, that puts Jacobs’ archive on shaky ground. But in practice, David Nimmer, the UCLA copyright lawyer behind Nimmer on Copyright, told the AP that lawsuits seem unlikely, largely because nobody involved is making money from the project.

Many artists have even treated Jacobs less like a pirate than like an obsessive documentarian who happened to preserve nights no one else bothered to save. And, some of those recordings have made their way into official releases.

One of these is the Replacements’ Tim: Let It Bleed Edition, released by Rhino in 2023.

Its companion live set, Not Ready for Prime Time, drew from Jacobs’ audience tape of the band’s January 11, 1986 show at Cabaret Metro, combined with the band’s soundboard recording.

Jacobs’ recordings had also already supplied much of Sonic Youth’s Hold That Tiger, bonus tracks on the Daydream Nation reissue, and releases by the Mekons, Wilco, Cap’n Jazz, and Built to Spill.

So the archive remains exposed in a legal sense, but the stronger story is how rarely anyone has chosen to act on that fact. For now, the law says one thing. The artists, in most cases, seem to be saying another.

“If I don’t do it, it’s lost forever,” Jacobs told Tone Madison. “There is a responsibility to history.”
