Episode notes
Learn By Recreating And Networking
- Be proactive: meet producers, ask technical questions, and then recreate sounds the next day to learn fast.
- Use shows and in-person networking to open session opportunities and build skill quickly.
Why K‑Pop Demos Need To Shine
- K‑pop demos must be almost record-ready because the industry expects polished, performance-ready demos.
- That high demo standard helped KPop Demon Hunters get greenlit, since the songs conveyed the film's sound and vision early.
Demo As Full Production
- Ejae showed early demos of 'How It's Done' that she fully vocal-produced and mixed herself in Ableton, sometimes layering hundreds of vocal tracks.
- She recorded crowd FX, harmonies, and complex stacks that served as record-ready demos used in storyboarding and screenings.
