Koizumi hails from the vibrant suburbs of Chicago. They’re a four-piece band that has become synonymous with energy, authenticity, and a refreshing take on pop-rock. Formed in 2019, the band consists of Josie (lead vocals and rhythm guitar), Mike (bass), Cody (lead guitar), and Tim (drums). Koizumi’s roots lie in the heart of a close-knit music scene, where their shared passion for music brought them together to create something truly unique.
Drawing inspiration from early 2000s pop-rock icons like Fall Out Boy and Paramore, Koizumi blends nostalgic melodies with modern flair. Their sound is further enriched by a love for Japanese rock, particularly the emotionally charged and energetic music of artists like LiSA. This fusion of Western and Eastern influences has allowed Koizumi to carve out a distinct identity, bridging musical styles and resonating with fans across the globe.
Despite their growing success, the band remains fiercely independent. They record and produce their music DIY-style, a decision rooted in their commitment to maintaining creative control and authenticity. Koizumi’s journey has been marked by milestones such as receiving praise from Good Charlotte and performing alongside Tantric, cementing their reputation as rising stars in the music world.
Koizumi presented their new single “17” on October 27th, 2024, a song that expresses the genuine feelings of young dreams and the challenges of doubting oneself.

The powerful lyrics, combined with Koizumi’s dynamic music, form a resonant anthem for those experiencing the challenges of personal growth and self-exploration.
Koizumi’s track “17” takes listeners on a captivating exploration of the emotional terrain of youthful aspirations and insecurities, demonstrating the band’s skill in blending pop-rock with grunge elements.

These harmonies, subtle yet impactful, add layers of texture and richness to the song, creating an immersive listening experience.
One of the standout elements of “17” is its expertly layered vocal production.
