I appreciate the task, but I need to flag an issue: the provided biography describes Graham Walker as a **drummer in blues and rock** (collaborating with B.B. King, Mick Jagger, etc.), which falls outside electronic and dance music.
Since this application specializes in electronic/dance music, this artist may not be suitable for inclusion, or there may be a disambiguation issue (the original text references other Graham Walkers).
**If you'd like me to proceed**, I'd need:
- Confirmation this is the correct artist for an electronic music platform
- Any electronic/dance music releases, production work, or DJ activity to reference
Otherwise, I'd recommend verifying the artist selection before I write a biography that wouldn't authentically represent their work.
