I don't have sufficient information about Keimo Hirvonen's electronic or dance music career to write an engaging biography for a music discovery platform. The source material only identifies him as a drummer from Helsinki without details about his work in electronic music, notable releases, collaborations, or contributions to the genre.
**To create an accurate biography, I would need:**
- Specific electronic/dance music projects or aliases
- Notable releases, EPs, or albums
- Record labels he's worked with
- Collaborations with other electronic artists
- His musical style and production approach
- Contributions to the Finnish electronic music scene
If you have additional information about his electronic music work, I'd be happy to rewrite his biography accordingly.
