I don't have sufficient information to rewrite this biography for an electronic and dance music platform. The original biography identifies 長田昌之 as a heavy metal drummer, which falls outside the scope of electronic and dance music specialization.
To create an accurate, engaging biography for a music discovery application, I would need:
- Confirmation of any electronic or dance music work
- Notable releases or projects in the electronic/dance space
- Collaborations with electronic artists
- Labels or platforms associated with electronic music
- Specific musical style or subgenre contributions
**Recommendation:** If this artist has electronic music credentials, please provide additional context so I can craft an appropriate biography. If their primary work is in heavy metal drumming, they may not be the best fit for this particular platform's focus.
