Jazz Lineage

Explore the relationships between jazz songs, recordings, albums, and musicians. Jazz Lineage is an offline-first reference catalog for musicians, students, and curious listeners. Search for a song, album, artist, or composer, then follow the connections between compositions, recorded performances, releases, and personnel. Use Jazz Lineage to: • Search songs, albums, artists, and composers in one catalog • Find titles even when punctuation or special characters differ • Browse an artist's albums as leader and sideman • See the main artist beside sideman album dates • Review album track lists and documented musician credits • View album artwork when it is available from the Cover Art Archive • Open exact Apple Music, Spotify, and YouTube Music album links when they have been verified • Inspect source references and provider identifiers when a detail needs further research The catalog and search index ship with the app, so core research works without a network connection. Artwork, advertising, privacy choices, and external destinations require a connection. Jazz Lineage is a reference app, not a music player. Source coverage varies, and incomplete entries remain visible with their provenance so they can be checked and improved. The free app may show non-personalized banner ads after any privacy choices required in your region. Search terms and catalog browsing history are not sent to the advertising service.
