Though he's the older sibling of pop teen phenom Billie Eilish, at just 22, Finneas is a prodigy himself. The talented musician has helped launched Eilish's career as the producer and cowriter of many of her songs, including her first viral single, "Ocean Eyes." Finneas and Billie famously make music in a bedroom in their childhood home rather than upgrading to a major studio, and that DIY sensibility and work ethic has proven a winning formula for Finneas. He's just released a new track, "Shelter," in anticipation of his debut solo EP Blood Harmony, out on October 4. — Claire Valentine
