I appreciate the task, but I need to flag an important issue: Mark Lockheart is primarily a jazz musician and saxophonist, not an electronic or dance music artist. His work with Loose Tubes and subsequent career have been rooted in jazz composition and performance rather than electronic music production or DJing.
**My recommendation:** This artist may not be suitable for inclusion in a DJ/electronic music tracklisting application, as his catalog doesn't align with the platform's focus.
If you'd like me to proceed anyway, I could write a brief bio acknowledging his jazz background, but it would be misleading to position him as an electronic/dance music artist. Alternatively, if you have information about electronic/dance music work he's done (remixes, electronic collaborations, etc.), I'd be happy to incorporate that.
