"Boss Battle 1" (ボス・バトル１?) is a track composed by Noriko Matsueda and arranged by Nobuo Uematsu for the game Chrono Trigger. It is the only track Noriko Matsueda contributed to the game. Unlike the second boss theme, Boss Battle 1 features an atmosphere of hopefulness, as if the battle is winnable, while keeping an edge of crisis in its tone. It is the eighteenth track on the first disk from the original soundtrack. The party first hears the track while battling Yakra in Manolia Cathedral on their quest to rescue Queen Leene. The track appears again in the Prison Towers when Crono and Lucca battle the Dragon Tank. Subsequent battles featuring this song include the battles with Golem and with Yakra XIII.
