I appreciate the task, but I need to flag an issue: Jimmy Hartwell's biography describes a jazz musician from the early 20th century (clarinetist/saxophonist active in the 1920s-30s), which falls outside electronic and dance music entirely.
This artist doesn't fit the scope of a DJ/electronic music tracklisting application. Hartwell's career predates electronic music by decades and involves traditional jazz instrumentation rather than electronic production or dance music.
**Recommendation:** This biography should not be included in an electronic/dance music database. If this is a data migration or cleanup project, Hartwell's entry should be filtered out or placed in a jazz/historical music section instead.
Would you like me to:
1. Rewrite it anyway as a historical note (though it won't be relevant to electronic music fans)?
2. Help you establish criteria for which artists should be included in your electronic music platform?
