Since debuting in 2013, the American anime web series RWBY has succeeded largely thanks to its lively, dynamic soundtrack by musician Jeff Williams. Sweeping instrumentals like “Round One” gesture toward the bucolic music of the Final Fantasy video games, while on the triumphant “World of Remnant,” violins and percussion conjure the epic settings of shows like Game of Thrones. Heavy pop songs like “It’s My Turn” and “Neon” feature tenacious vocals from Williams’ daughter, Casey Lee Williams.
