/analyze-artist

Purpose

The /analyze-artist command performs comprehensive discography research for a musical artist, producing a structured YAML profile that identifies creative eras, recommends catalog organization, and guides collection development. This command is the entry point for the Media Curator framework's artist-centric workflow.

Parameters

Required

<artist_name>

• The artist or band name to analyze
• Supports aliases and common alternate names
• Example: "Twenty One Pilots", "Radiohead", "Kendrick Lamar"

Optional

--scope <scope_type>

• Controls the breadth of analysis
• Default: complete
• Options:
  • complete - Full discography across all eras
  • era:<era_name> - Focus on specific creative period (e.g., era:Blurryface)
  • style:<style_name> - Focus on releases matching style tag (e.g., style:acoustic)

--depth <depth_level>

• Controls research thoroughness and time investment
• Default: thorough
• Options:
  • quick - MusicBrainz canonical releases only, basic era detection (2-5 min)
  • moderate - MusicBrainz + Discogs cross-reference, standard era analysis (5-15 min)
  • thorough - Full multi-source research, narrative analysis, gap identification (15-45 min)

--output <file_path>

• Specify custom output location for YAML profile
• Default: .aiwg/media-curator/profiles/<artist-slug>.yaml

--include-unofficial

• Include bootlegs, demos, and unofficial releases in analysis
• Default: false (official releases only)
• When enabled, adds unofficial section to YAML output

--interactive

• Enable interactive mode for era boundary decisions
• Default: false (automated analysis)
• Prompts user at ambiguous era transitions for input

Workflow

Phase 1: Artist Identification

1. Query MusicBrainz for artist MBID using provided name
2. Resolve aliases and display disambiguation options if multiple matches
3. Retrieve artist metadata (active years, genres, relationships)

Example Query:

curl "https://musicbrainz.org/ws/2/artist/?query=artist:Twenty%20One%20Pilots&fmt=json"

Phase 2: Release Discovery

1. Fetch complete release groups from MusicBrainz
2. Cross-reference Discogs for variant pressings and bootlegs (if --include-unofficial)
3. Filter by release type (album, EP, single, live, compilation)
4. Sort chronologically by earliest release date

Data Points Collected:

• Release title and MBID
• Release date (year-month-day)
• Release type and status (official, promotion, bootleg)
• Label and catalog number
• Track count and total duration
• Associated credits (producers, featured artists)

Phase 3: Era Detection

1. Analyze temporal clustering of releases
2. Identify lineup changes, label transitions, genre shifts
3. Review Wikipedia and AllMusic for contextual markers
4. Detect narrative arcs and concept album sequences
5. Establish era boundaries with supporting evidence

Detection Signals (see @$AIWG_ROOT/agentic/code/frameworks/media-curator/agents/discography-analyst.md for complete signal taxonomy):

• Musical evolution (genre tags, production style)
• Contextual changes (label, location, collaborators)
• Narrative markers (artist statements, concept albums)
• Temporal patterns (recording gaps, intensive output periods)

Phase 4: Special Collections Identification

1. Identify narrative arcs (concept album sequences, trilogy structures)
2. Detect acoustic sessions, live recordings, remix projects
3. Map collaborations and featuring appearances
4. Highlight demo collections and pre-label material

Phase 5: Catalog Structure Recommendation

1. Design directory hierarchy reflecting eras and special collections
2. Define organization principles (chronological, thematic, hybrid)
3. Recommend segregation of unofficial material
4. Provide implementation-ready file system structure

Phase 6: Gap Analysis

1. Compare collection against canonical discography
2. Identify missing releases by priority (essential, recommended, optional)
3. Note availability status (in-print, out-of-print, digital-only, unreleased)
4. Flag high-value acquisitions for collection completion

Phase 7: Output Generation

1. Structure findings into YAML schema (see Output Format section)
2. Write to specified output location or default path
3. Display summary report with key findings
4. Provide next-step recommendations

3. Combined "Mid-Period Beatles" (1965-1967) including Sgt. Pepper's

Enter selection (1-3) or provide custom era name:

User input guides final era structure in YAML output.

Example 6: Style-Focused Analysis

/analyze-artist "Bon Iver" --scope style:acoustic --depth moderate

Output: Analysis focusing only on acoustic or folk-oriented releases, filtering out electronic experiments like "22, A Million". Useful for genre-specific collection curation.

Saved to: .aiwg/media-curator/profiles/bon-iver-acoustic.yaml

Integration with Media Curator Workflow

The /analyze-artist command outputs YAML that feeds downstream Media Curator agents and commands:

1. Collection Planner (/plan-collection): Uses gap analysis and priority rankings to build acquisition roadmap
2. Metadata Enricher (/enrich-metadata): Applies MBIDs, Discogs IDs, and era tags to existing music files
3. Quality Assessor (/assess-quality): Prioritizes high-significance releases for quality upgrades (lossless, remaster, vinyl rip)
4. Catalog Organizer (/organize-catalog): Implements recommended directory hierarchy, moves files into era-based structure
5. Listening Queue Generator (/queue-listening): Creates chronological or thematic playlists based on era structure

Invocation by Discography Analyst Agent

When the Discography Analyst agent is active, /analyze-artist can be invoked implicitly through natural language:

User: "Analyze Twenty One Pilots discography"

Agent Response: Executes /analyze-artist "Twenty One Pilots" --depth thorough and returns YAML profile with summary.

User: "Focus on the DEMA era"

Agent Response: Executes /analyze-artist "Twenty One Pilots" --scope era:DEMA and provides detailed breakdown of Blurryface/Trench/Clancy trilogy.

Performance Characteristics

| Depth Level | Data Sources | Avg Time | Output Size | |-------------|--------------|----------|-------------| | Quick | MusicBrainz only | 2-5 min | 5-15 KB | | Moderate | MusicBrainz + Discogs | 5-15 min | 15-40 KB | | Thorough | MusicBrainz + Discogs + Wikipedia + AllMusic | 15-45 min | 40-150 KB |

Factors affecting duration:

• Discography size (10 releases vs. 100+ releases)
• Era complexity (single-era artist vs. 6+ distinct periods)
• Unofficial material inclusion (bootlegs require extensive cross-referencing)
• API rate limits (MusicBrainz: 1 req/sec, Discogs: 60 req/min)

Quality Standards

• Completeness: All officially released material identified (studio albums, EPs, singles, live albums, compilations)
• Accuracy: MBIDs and Discogs IDs verified against canonical sources
• Coherence: Era boundaries justified with multiple detection signals (musical, contextual, narrative, temporal)
• Actionability: Catalog structure directly implementable in file systems (valid directory names, logical hierarchy)
• Transparency: Classification decisions documented with rationale (why this release is "studio" not "demo", why this era boundary here)

Limitations

• Requires internet access for MusicBrainz, Discogs, Wikipedia, AllMusic queries
• Era identification is interpretive; command provides evidence-based recommendations, not absolute truth
• Bootleg and unofficial material may have incomplete, conflicting, or absent metadata
• Very recent releases (< 6 months) may lack sufficient critical or historical context for era placement
• MusicBrainz and Discogs may have incomplete data for regional or non-Western artists
