crib, my childhood

Kobacchi Ryo, who has walked with music as a rapper up to the present, felt the need to look back to his origins.

In his third year of junior high school, he met a classmate. He was a singer who posted his singing voice on 'Nico Nico Douga'. He said to Kobacchi Ryo, "Your rap is perfect. Why don't you record it at my house?"

I was surprised when he invited me to his house.

What is his production environment?
And what were his intentions?
