FEVER 333 formed in Inglewood, California in 2017, founded by ex-Letlive vocalist Jason Aalon Butler alongside guitarist Stephen Harrison (the Chariot) and drummer Aric Improta (Night Verses), performing their first show in a U-Haul truck in a donut shop parking lot on July 4th. The band's sound merges rap metal, post-hardcore, and political punk in the tradition of Rage Against the Machine, addressing racism, systemic violence, and social inequality with pointed directness on their debut EP Made an America (2018) and full-length Strength in Numb333rs (2019). Both Harrison and Improta departed in 2022, and Butler rebuilt the band with a new lineup — including former The Mars Volta drummer Thomas Pridgen — releasing the second album Darker White in 2024.

Finch are a Temecula, California post-hardcore band whose debut made them one of the defining acts of the early-2000s emo and heavy alternative crossover. Formed in 1999, the group broke through with What It Is to Burn, an album that joined melodic hooks, screamed intensity, and polished production in a way that appealed to punk, emo, and heavier rock audiences at once. Say Hello to Sunshine complicated that success with darker, stranger arrangements and a less immediately accessible post-hardcore sound, earning a reputation as a cult record after initially dividing listeners. Later reunions and releases kept the band's name active, but Finch's core legacy remains the tension between the cathartic directness of their debut and the restless ambition that followed. They fit punk and metal-adjacent scope through post-hardcore, screamo, and alternative rock heaviness. Finch's best songs use contrast sharply: clean vocals break open into screams, bright guitar lines turn jagged, and choruses carry both romance and collapse. The band captured a moment when emotional rock was becoming heavier, more polished, and more volatile.
