KOSER
galactic glitter grunge
KOSER is an alternative rock band known for fusing brooding textures with explosive energy. 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. 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. Pairs well with Mannequin Pussy, Radiohead, and Hayley Williams.

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.​
