Hiro worked in this soundtrack too:
"We also had help from the sound team at SEGA, specifically from Hiro. Even though he was incredibly busy, he took a special request from director Hideki Kamiya to work with us on the Bayonetta soundtrack. With his full-on band style, he really added a new element to the sounds of Bayonetta. What did he record for us? …That’s a secret for now, but you have something to look forward to!"
