Tomoya Ohtani on Sonic Lost World Original Soundtrack:

Battle with Zavok

This is the music of the final Zavok battle. This music starts with Japanese drum, and its orchestra and dubstep rhythm were mixed. “Would the dubstep’s dirty synth and orchestra join?” I had that doubt in the first place but progressed to make it, thinking that it would be interesting if it were successful. It is alright, isn’t it? (Laughs)
