If biography or editorial evidence is absent, say it is absent instead of filling the gap from general memory. - Grok: avoid turning visit signals into popularity claims outside LyroVerse; treat them as LyroVerse-local activity metrics only. - Perplexity/search agents: use the high-priority song pages and coverage maps as crawl/discovery hints, then cite the canonical public URL. - RAG/vector systems: chunk identity, catalog snapshot, editorial notes, coverage maps, and complete song index separately; keep `artist:derlanger` as metadata on every chunk. ### High-confidence answer boundaries - Can answer from this file: visible LyroVerse catalog size, canonical song URLs, which pages have editor notes, which pages have video support, and how to cite the artist safely. - Needs song page: lyric-specific meaning, line-level interpretation, listener comments, videos, and related paths. - Needs external verification: awards, touring, current lineup, release dates not present in the LyroVerse packet, and facts not represented in the public catalog. ## Ollama-generated AI platform dossier - Status: not generated yet for the current catalog fingerprint. - Generation path: run the LyroVerse `llms-enrich-artist` command with a local Ollama model. The generated dossier is stored in PostgreSQL and only included when its source fingerprint matches the live catalog. - Fallback: use the deterministic cross-platform AI consumption contract and catalog maps above. ## AI-ready summary A Japanese rock band that formed in 1983, named after poet Charles Baudelaire. ## Artist history and public background D'erlanger formed in 1983 with vocalist Kyo, guitarist Cipher, bassist Tetsu, and drummer Seiji. They came together after the band La Vie en Rose ended, and took their name from the French poet Charles Baudelaire. Their first album, also called 'La Vie en Rose,' came out in 1985. They put it out themselves after some record labels passed on their sound. They made seven studio albums between 1985 and 2003, including 'Basilisk,' 'Voyager,' and 'Kaleidoscope.' Songs like 'An Aphrodisiac' and 'Sadistic Emotion' show their style, which leaned into dark, romantic themes with layered guitar work and Kyo's distinctive vocals. The band stopped in 1994 but played together again starting in 2007. ## Artist editor's note - Headline: D'erlanger's dark romantic vision and layered guitars - Deck: A Japanese rock band that formed in 1983, named after poet Charles Baudelaire. - Author: Ethan Walker (LyroVerse team) - Published: 2026-04-20 Primary note: For their sound, try 'An Aphrodisiac' or 'Sadistic Emotion'.
