RZA (Robert Fitzgerald Diggs) is a Grammy-winning producer, rapper, and author who's basically the backbone of Wu-Tang Clan—he's produced nearly everything they've put out, from their main albums to solo projects and affiliate work. Beyond hip-hop, he's become known for film scoring and acting, which honestly surprised a lot of people who only knew him from the group.

Most casual fans probably recognize his name from the Afro Samurai soundtrack, which he scored and which introduced a lot of people to his cinematic side. He's also ventured into directing and screenwriting, though producing remains his main thing. His Grammy wins speak to his influence across different genres and mediums.

He's essentially defined Wu-Tang's sound from the beginning, making him one of hip-hop's most important figures even outside the group's sphere.
