Editorial interest 84/100 Selection signal · not a rating of the site

A fan-built index for exploring improvisational bands, musicians, historic performances, songs, and recording sources.

Landing page captured for the 2026-10-31 issue.

For: Fans tracing improvisational bands, performances, and recording sources
Worth noticing: Its protocol says every connection needs evidence, future shows need dated sources, and unknown is better than invented.

Field notes

Search spans artists, side projects, historic shows, songs, tape references, concert snapshots, and sources, with links leading into connected archive pages. The browser-saved watchlist tracks artists and their known projects or listed shows. The site also directs visitors to external archival partners and states that linking to their work does not grant permission to copy it. Tour information is a curated snapshot, not a live event or ticket feed.
