⚠️ Sponsor Highlight ⚠️
Providing the backline (shipping all the way from Germany) for this year's fest is our favorite Sonic Doom Device producer: Lichtlaerm Audio

We'll be featuring custom Lichtlaerm cabinets and their signature Prometheus amp. If you are not aware, this is insanely fu***ng cool.

Not only do they perfectly match the aesthetic we wanted for the fest visually, we are very particular about quality, and knew that these would deliver and far surpass expectations. As we are a festival presented by a music producer, there was no cutting corners in this arena. There is currently a waitlist for their Prometheus tube amps, but you can snag their highly-sought-after custom pedals on their website now.

Who the hell is behind Flatline Fest? Well, it's these two well-lit humans, Dave Otero & Chelsea Lowe.

Dave Otero is the mastermind behind Flatline Audio and has been producing, mixing, and mastering extreme metal as literally his only job for decades.

Chelsea Lowe is the weirdo behind these posts and the entreprenihilist behind FootClothes. She's a long time performer in both the metal and magic worlds and feels weird writing a post about herself in the third person. She works alongside the Dave to bring the business, the branding, and the puns.

They are getting married the day before the festival because they are insane.

Flatline Audio - Producer Dave Otero

Handling the merchandising for this year's Flatline Fest will be none other than FootClothes. Is it because one of the promoters of Flatline Fest also owns a sock company?

Yes, that is precisely why.

But we'll be one of the only metal festivals with frickin' socks alongside some locally printed shirts (unisex AND female cuts) as well as a small handful of hoodies and patches, so we're going hard. Stay tuned for those announcements and while you wait, go buy some socks. Thanks.

Our next sponsor announcement: Metal Blade Records.

Flatline Audio has a long history with Metal Blade, and we’re honored to have them on board for the first Flatline Fest.
