I appreciate the task, but I need to flag an important issue: Dave Mattacks is a rock and folk drummer with no significant career in electronic or dance music. His work is primarily in acoustic folk-rock with Fairport Convention and other traditional music contexts.
**Recommendation:** This artist doesn't fit the scope of a DJ/electronic music tracklisting application. Including him would be misleading to users searching for electronic and dance music content.
If you need this biography rewritten for a *general* music platform or folk/rock database, I'm happy to help with that instead. Otherwise, I'd suggest excluding this artist from an electronic music-focused service to maintain platform integrity.
