The Zeta Project

Working concurrently with the final season of Batman Beyond, for Zeta's first season, the Walker team worked to compose original music for each episode that blended the sound of a live orchestra composed of musicians hired from American Federation of Musicians Local 47, with more contemporary electronic elements the team recorded in their own studio.

According to McCuistion, "Each episode was a different take, musically, and there were some threads of course, but I remember several of them having different musical environments, and that was really interesting creatively. [...] it certainly didn't share any of the flavor of Batman Beyond in terms of music, I don't think.
