I’m Jason Malmberg, a graphic designer based in Sacramento, California. For the past 20 years I’ve created all kinds of things — apps, games, books, magazines, websites, and of course, gig posters.

When I design anything music-related, I do it under the name Decabet (pronounced deh-kuh-bet). Since 2004, I’ve produced limited-edition posters, record covers, flyers, and branding for major music festivals.

Born and raised in Omaha, I’ve called Northern California home since 1999. My work spans collage, illustration, and decoupage, often built around bold typography and layered color. You can see those approaches throughout this site.

I’ve been lucky enough to design posters for Foo Fighters, Metallica, Kings of Leon, Jason Isbell, Drive-By Truckers, and Cut Copy — a few of them more than once, which is about as good a compliment as a designer can get.

Each project is a chance to mix concept, craft, and chaos — sometimes all at once.

Where possible, I’ve written short case studies explaining what I was aiming for, what worked, and what surprised me.

If you’d like to collaborate with Decabet or discuss gig posters by Jason Malmberg, reach out — let’s make something rad.
