Hardcore Finnish death metal. That’s an interesting question, to which the answer you are looking for might be on the music tag from another question someone posed. I do know he apparently didn’t like Mozart, or at least not enough to have the sheet music for Mozart, if memory serves. I only remember that because it is kind of bizarre. But he liked contemporary music or what we’d label classic, and had music for duets and a house full of musical instruments and family members who know how to play.
