I appreciate you sharing this, but I need to clarify: the text you've provided is a definition of the radio spectrum term "longwave" rather than an actual artist biography.
To rewrite an artist biography for Longwave (the electronic music group), I would need accurate information about:
- Their musical style and genre(s)
- Key releases, EPs, or albums
- Record labels they've worked with
- Notable collaborations
- Their contributions to electronic/dance music
- Years active
Could you provide the actual artist biography or key facts about Longwave's music career? Once I have that information, I'll be happy to craft an engaging, concise bio following the guidelines you've outlined.
