ABOUT KOSER:

_D6A3544.jpg

KOSER is an alternative rock band known for fusing brooding textures with explosive energy. With roots in Philadelphia, the group draws from post-punk, grunge, and electronic influences to craft a sound that’s delightfully soulful and sonically rich. Their music balances heavy, cinematic atmospheres with razor-sharp hooks and honest lyricism. It's a journey that’s as introspective as it is intense. Formed in 2022, KOSER is made up of 5 virtuosos whose live shows channel the same energy as their recordings— moody, immersive, and sneakily powerful.

MORE BIO

 

K. Koser, lovingly known as Koser, is the band's namesake! Writing songs since age nine, Koser chased the legacies of fierce, female-led bands like Paramore, Heart, and Fleetwood Mac. Battling performance anxiety and addiction made the dream feel out of reach—but she kept singing anyway. In 2018, newly sober, she entered a grueling 3-month vocal competition—the first time she’d ever performed without substances—and won. Shocked. Sober. First place. That moment lit a fire she’s never let go of.​

​

Meet 2025 KOSER— a funky five piece that brings the house down. Every Single. Time. Don’t let the warm smiles and charisma fool you… these folks can go from sweet rnb to grungetacular in 2 seconds flat! It’s how they’ve played events like WMMRbq, Musikfest and Ladybug Fest; and opened for The Family Crest, Margaret Glaspy, and Fletcher! You want sax? On it. You like soulful vocals with a bite? Done. You want a comedy routine in the middle of a sick Thin-Lizzy guitar solo? Heard! Buckle up friends, you never know where this train stops next!
