Sending tremendous love and congratulations to my brother @miguelgandelman for your incredible work at the 2026 Bad Bunny halftime show…winning you the Outstanding Music Direction at the 79th annual Emmy awards! Thank you for including me as part of your team. 🙏🏼🙏🏼🙏🏼

And a huge congrats to the live and broadcast sound team and the much deserved win of an Emmy for Outstanding Sound Mixing for their incredible work making it all come together on the day!

I’m honored to have participated in this process on the studio side and to have mixed the tracks that Benito, Gaga and Ricky Martin performed to.

I must say that though it’s rare that we find ourselves working on projects that receive such profound recognition, this project felt different from the start. It felt like a freight train chugging down the tracks, with the most driven and focused creatives flying down the rails with it, and we were all just privileged to be on board.

Congrats to all involved! Thank you Miguel for being the giant you are. Thank you @sharafentwistle for your assistance. And thank you Benito. by @jonrezin

About last night…. I’m still floating. 

It’s one thing to get the chance to work with some of the world’s biggest stars, it’s entirely another to have the chance to contribute to something that carries so much meaning for so many. I’m not only speaking about our brothers and sisters in Puerto Rico who are getting an opportunity to shine on a global stage, unapologetically Puerto Rican, unapologetically American, but for us as a country. 

I’m continuing to learn what this performance meant… both in terms of symbolism and the story that took place, but what it meant in the lives of so many of our Spanish speaking brothers and sisters. People who, right now, have targets on their backs… One thing I can be sure of, celebration can be a form of self care… and celebrating Puerto Rican identity, culture, and value on the world-stage has opened people’s hearts and given others the permission to feel they too can celebrate who they are. 

Bad Bunny is one of the best there is… and his message of love, celebration of diversity, and recognizing our diversity as a source of strength that should bring us together, is one of the most timely messages we need right now. Last night, we were all united. In love, in culture, in music, with Puerto Rico. 

Thank you Bad Bunny for bringing your heart and message to this world stage.. @ladygaga for killing that salsa version of Die With A Smile, @ricky_martin for delivering such a poignant version of Lo Que Le Paso A Hawaii, and thank you @miguelgandelman for entrusting me with helping you deliver your vision. I am infinitely humbled and honored to have played a small part in this incredibly important moment. 

- Jon

p.s. An incredible thank you to @sharafentwistle for always having my back and helping me deliver on such monumental visions. 
And lastly, but certainly not last, none of this would be possible without the support of my loving wife @auntieclare_rezin and three incredible children. taken in America by @jonrezin

I’ve gotten a lot of great feedback on CRATE in the last couple days… And a lot of great questions about how it works.

Here’s a basic rundown of the app. (More depth covered in video):
- 60-90% smaller sends, receives and storage
- Completely lossless pipeline
- Files are verified on send and receive
- 100% identical to what you sent
- DAW agnostic. Files relink perfectly

Let me know if you have any questions in the comments and I’ll be happy to share the answers.

Thanks again for your support. LINK in Bio. Download free. taken in CRATE by @jonrezin

Some of you may know that I created a new archive format called crate… But what some of you may not know is that, aside from making sessions and audio 60 to 90% smaller, it does it lossless and it can be used for session backups. In this impromptu video I will show you how it works… and show you how I use it in my backup workflow. Give it a shot and see if it helps you. I spent just a few hours and recovered over a terabyte of space. taken in Vault by @jonrezin

What a blessing… Today’s backup day and I’m cleaning off some old sessions from my drives and putting them in the archives and I’m just astounded at the artists that I’ve had the chance to work with and the great records that I’ve had a chance to be a part of. Feeling super blessed. #jpop @boakwon @baekhyunee_exo @cbx.exo._ @weareone.exo @girlsgeneration @miyavi_ishihara @prizmax_tokyo_official @shinee @shinee_jp_official @superdragon_official @taemin_xoalsox taken in Tokyo, Japan by @jonrezin

Hola. Habari. Olá. Bonjour. 안녕하세요. Merhaba. Kumusta. Ciao. Cześć. こんにちは. Hallo. 你好. Xin chào. Hej. مرحبا.

Crate 1.7 is out — and it speaks your language. All 18 of them. 🌍

Every screen, from pack to restore: Arabic, Chinese, Dutch, English, Filipino, French, German, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Spanish, Swahili, Swedish, Turkish and Vietnamese. Crate offers your language the first time it opens — and right-to-left layouts are properly mirrored.

Also in 1.7:

🎬 Video-editor turnovers (AAF + OMF) now pack dramatically smaller — every file still verified bit-exact on both ends
🔔 Know the moment a job is done — a notification you can click to reveal the file, a completion sound (16 cues, or bring your own), a badge on the icon
📦 Pack your way — skip the usual desktop clutter, or keep an exact clone of every last file
⚡ Faster and lighter everywhere — picture-reference sessions stop wasting minutes on pointless recompression, and packing uses about 40% less memory

Your session. Byte for byte. In your language.

Update from inside the app, or download at the link in bio.

So thrilled with how @alessiasmusic performance came out for the opening of the World Cup in Canada 🇨🇦. It was a really fun medley to mix the tracks she performed to.

As always, thank you @miguelgandelman taken in FIFA World Cup by @jonrezin

It’s been a rich summer!

I had the honor of mixing the performance tracks for the first Latina to ever headline Coachella… the incomparable @karolg 

Such a rush to see my work on one of the biggest stages in the world. Congrats to Karol for being the first and being unapologetically Latin. She is kicking the door open for so many who will follow after her.

One week since we soft-launched Crate, and the response since has been incredible. 🙏🏼

For those that move massive sessions between studios, collaborators, or continents, CRATE 📦 is a lifesaver. It losslessly transforms sessions and audio into 59-89% smaller packages (Crates are significantly smaller than ZIP or RAR) and restores bit verified on the other end!

Drag a folder into the app to pack or unpack. Use the Finder menu bar. Or right-click any folder and pack it on the spot. It’s fast and dead simple, but it’s the engine that makes it tremendously powerful.

Crate is audio-aware and 100% lossless. FLAC and WavPack encoding, deduplication, and residual detection pack huge sessions down to sizes you won’t believe. Then we check every file bit for bit with SHA-256 on both ends. No quality lost. No silent corruption. What you send is exactly what they open.

ZIP and RAR only see data. Crate sees your sessions.

“This last session was like 12GB and it compressed down to like 500MB.” Miguel Gandelman (Music Director: Bad Bunny, Karol G, The Masked Singer)

Built for the nomad producers, mixers, and mastering engineers moving real lossless audio, the ones who don’t get to blame the network anymore.

Unpacking is free forever, for everyone. Your first pack is on us. After that, pay once and pack forever.

This is CRATE. 📦

If it saves you time, drop a comment and send it to someone who needs it. it would mean the world. 🌎 🙏🏼

so…. I never imagined this day would come…

but I’m thrilled to share that my first audio tool is out in the world.

This came as inspiration as I am constantly dealing with challenging internet at the least opportune of times and yet deadlines have to be hit as many people are depending on the work arriving on time.

I’ve also been working with a number of incredible creators from developing countries and I regularly hear about the costs of data and how it can be a huge burden. They have to make unthinkable choices.. eat that day or send the session. This isn’t a choice that should have to be made.

I cant fix the internet or all the world’s problems… but what I can do, is fix what we are sending.

I’m honored to share CRATE with you. 📦

I built Crate because a 4 GB session shouldn’t cost someone a day’s pay to download/upload. In much of the world, mobile data runs $3–10 a gigabyte — and it’s often the only connection there is. So a producer in Lagos, a mixer in Manila, an engineer on a mountain in Medellín all hit the same wall: the work is ready, their bandwidth isn’t.

And if you’re a digital nomad living on café Wi-Fi and hotel networks? This is your unfair advantage. Pack a session straight from your right-click menu, drop it in the menu-bar Quick Bay, send the smaller file over whatever you already use, and stay fast on networks that were never built for what we all need.

Crate shrinks sessions 59-89% — completely lossless, every single sample bit-for-bit identical — then SHA-256 verifies every file on both ends. No quality lost. No silent corruption. No “re-send that stem, it came through with a click.” Zip and RAR weren’t built for this. Crate was.

It’s a tool, not a platform. No account. No subscription. Works offline. Receiving is always free — anyone, anywhere can open what you send.

This is how audio should have always moved. 🌍

I hope you enjoy it. If so, drop a line and tell a friend. It would men the world to me.

🙏🏼🙏🏼🙏🏼
