Genre-bending Boston sibling duo Brevin Kim mash together pop, rock, alternative, and hip-hop. They started making music together when barely into double digits, initially inspired by rap but later by indie acts like Kings of Leon and Bon Iver, with Brendan Paulhus focused primarily on beatmaking, while Callin Paulhus contributed most of the lyrics. Fascinated by experimenting with production, they were unafraid to mash together ideas from totally unrelated genres, but always with a focus on catchy hooks. The pair started uploading tracks in 2017, releasing a slew of free albums and EPs that gradually built up Internet buzz and accrued hundreds of thousands of streams. In 2020, they made their major-label debut with the EP Metallic Body Language, a collaboration with similarly genre-mashing Delaware rapper Lil West.
