Sombr writes or co-writes essentially all of his own material. Multiple interviews and profiles in 2025–2026 consistently describe him as a self-writer and self-producer who creates 100% of his records, with collaborators more advisory than foundational to the songwriting process. He even discusses isolating songwriting as part of his creative method in several features. If you’d like, I can pull direct quotes from those pieces and note the sources.
Key findings (high level):
- Sombr is widely described as self-writing and self-producing his music, with limited or no external co-writers on many tracks [source coverage from industry outlets published in 2025–2026].
- Interviews emphasize his solitary writing routine and the intensity of maintaining that independence as a core aspect of his artistry [sources from Billboard, Hollywood Reporter, and NPR-related profiles].
- In industry podcasts and press, critics and hosts frequently frame him as a 100% writer-producer who crafted his breakout songs largely on his own, reinforcing the narrative that he “writes every record himself” [podcast and feature coverage].
If you want precise attributions, I can compile a short list of recent articles and pull exact quotes with citations.
