To his friends and family, he goes by Grant Kwiecinski, the 28-year-old kid from north Detroit who grew up on a healthy diet of American funk, golden-age hip-hop, and dance music; the curious producer who first began making future-forward music during his formative years at Michigan State University, only to permanently abandon the classroom for the dance floor; and the fun-loving dude who’s the life of the party at every damn party. To the rest of the world, his name is GRiZ, the Denver-based multifaceted artist who’s funkin’ up dance floors worldwide with his self-described “future funk” sound, which mixes electronic music with his fiery live saxophone, energetic funk, and sweeping electro-soul.
