Earthbound is a 1990s Super Nintendo role-playing game in which Ness visits eight Your Sanctuary locations, each guarded by a powerful Sanctuary Guardian boss. The battle music for those encounters, credited to composers including Keiichi Suzuki and Hirokazu Tanaka, uses the console's distinctive sampled sound to make each fight feel strange and urgent. Long after its original release, the game gained a devoted cult following through re-releases and online nostalgia, and its boss themes are now reused in gameplay videos, edits and streams to signal a serious, climactic confrontation.
