When I was a DJ and working in the music industry as a music producer, I used to have my own studio in Osaka. Since the studio was in the basement of a building and I would make music loudly because the tracks I used to make were dance music and making in an environment where I could put out a lot of sound was really important for the career. As a DJ, practicing your performance in the volume as much as a club was also worth it because playing DJ at huge volume is absolutely different from playing at soft volume so you have to get used to the environment.
