I appreciate you providing this example, but I should note that Jeff Williams (born 1950) is primarily known as a jazz drummer rather than an electronic or dance music artist.
Based on your guidelines asking me to focus on electronic and dance music careers, this biography falls outside my specialization area. A rewrite would need to either:
1. **Acknowledge the mismatch**: Jeff Williams is a jazz percussionist, not an electronic/dance music artist, so a rewrite focused on EDM contributions wouldn't be accurate.
2. **Suggest clarification**: Is there a different Jeff Williams who works in electronic music you'd like me to profile instead?
If you'd like me to practice the rewriting format, I'm happy to work with an electronic music artist biography. Or if Jeff Williams has electronic music production work I'm unaware of, please share those details and I'll rewrite accordingly.
