FEVER 333 is an American rock band formed in Inglewood, California, in July 2017, consisting of former Letlive vocalist Jason Aalon Butler, guitarist Stephen Harrison from The Chariot, and drummer Aric Improta from Night Verses. The band quickly gained attention with their debut EP, Made an America, released on March 23, 2018, which showcased their energetic blend of punk rock and hip-hop influences. Their first full-length album, Strength in Numb333rs, followed in 2019 and was well-received for its politically charged themes and dynamic sound. FEVER 333 is known for their activism and socially conscious lyrics, often addressing issues like racism and inequality. Following the death of George Floyd in 2020, they released the live performance "Long Live the Innocent," with proceeds supporting organizations like Black Lives Matter. In October 2022, Harrison and Improta announced their departure from the band, leading to a lineup change that introduced new members Brandon Davis, April Kae, and Thomas Pridgen. With their music categorized as rap rock and trap metal, FEVER 333 continues to push boundaries and engage audiences through both their recordings and live performances.
