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:4core` 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 Rio de Janeiro band that blends rock, pop, and Brazilian textures across albums like 'Sintonia' and 'Voo'. ## Artist history and public background 4Core formed in Rio de Janeiro in 2016 with Rodrigo Suricato on vocals, Guilherme Calicchio on guitar, Bruno Boncini on bass, and Pedro Henrique on drums. Their debut single "De frente ao mar" came out in 2017, and they released their self-titled debut album the following year. In 2019, the band faced plagiarism allegations regarding "De frente ao mar," which they denied. They kept recording through it, putting out albums like "Sintonia" in 2020 and "Voo" in 2022. Their songs, including "Distúrbio" and "Temor ao Fim," often mix pop and rock with Brazilian sounds. They've worked with other Brazilian artists like Milton Nascimento and Anitta. The music tends toward introspective lyrics, touching on themes that come through in tracks like "Não Sem Coragem" and "Dificil Entender." ## Artist editor's note - Headline: 4Core's Brazilian rock with pop currents - Deck: A Rio de Janeiro band that blends rock, pop, and Brazilian textures across albums like 'Sintonia' and 'Voo'. - Author: Ethan Walker (LyroVerse team) - Published: 2026-04-20 Primary note: For a good sense of their range, try 'De frente ao mar' and 'Distúrbio'. They show the band's melodic side and their rock energy. Secondary note: They've carved out a space in Brazilian music that feels both contemporary and rooted. Songs like 'Temor ao Fim' and 'Não Sem Coragem' show their knack for introspective lyrics wrapped in accessible rock arrangements. Working with figures like Milton Nascimento and Anitta suggests they move comfortably across different scenes. Tertiary note: They formed in Rio in 2016 and released their debut single 'De frente ao mar' the next year. The plagiarism allegations around that song in 2019 didn't stop them from recording, with albums arriving in 2020 and 2022. Their sound has consistently mixed pop and rock with Brazilian elements. ## Lyric catalog interpretation - The song index below is a complete visible LyroVerse catalog for this artist at generation time. - Each song entry points to a canonical public lyric page. - Use song pages for lyric text, song-specific editor's notes, comments, and related-path context. - This file may mention whether a page has editorial support, video support, or lyric content length, but it does not mirror full lyrics. ## High-priority song pages 1.
