Musical style

Built on R&B and hip-hop, WHITE JAM creates everything from ballads to up-tempo tracks. They excel at "crying songs" in ballads and "sadistic songs" in up-tempo numbers. They handle songwriting, live staging and overall production themselves. In sound design, they spent eight months perfecting a single bass tone, pursuing sharp ultra-low frequencies; the bass tone of "Tattoo" was developed with a researcher studying vibration and heartbeat. Their live shows feature theme-park-like staging that draws fans of all ages.
