The Far Shore
Six-degrees games always ask how close — how few handshakes from A to B. Nobody ever asks the opposite question. Start at Quincy Jones, arguably the best-wired musician of the recorded era, and walk outward across every "played on the same recording" and "in the same band" link in MusicBrainz. 1.33 million artists are reachable. How far away is the farthest one?
The answer: the connected musical universe is fourteen introductions wide, and it is crowded in the middle. Half of everyone sits within three hops of Quincy; 99.95% within seven. Then the long tail thins to absurdity — 263 artists at ten hops, 27 at twelve, and at the very edge, at fourteen hops, exactly two people.
Walking to the edge
Who lives on the far shore? Follow the actual shortest paths and the answer turns out to be two different kinds of remoteness:
This is the second of the two paths, and it is a time machine. Two hops take you out of Hollywood (Soul Bossa Nova → Lalo Schifrin → a Madrid symphony orchestra), and from there every remaining step burrows deeper into 1920s Spanish zarzuela and revue theatre — chotis, foxtrots, and rumbas from shows that closed before electrical recording matured — until the path runs out at Vicente Mauri Soler, who sang a "Persian song" in the 1922 revue Arco iris, and after that, nothing. The far shore of the session universe is not a hermit with a four-track. It is the past: a scene fully recorded, fully entered, and connected to the present by one thin thread of orchestras.
The other fourteen-hop endpoint, Keiss, is the opposite kind of far: the path to him leaves the mainstream through Michael Jackson and Akon, then tunnels through six layers of present-day netlabel noise artists who mostly collaborate with each other. Remoteness comes in two flavors — long ago and deep underground — and the graph can't tell the difference until you walk the road.
The wormholes won't close
One more experiment. The reason distances are so short in the middle is supposedly the mega-collaborations — charity singles that put half the industry on one tape. Miles Davis and Bob Dylan really are one recording apart: both played on "Sun City," Artists United Against Apartheid,
- Quincy Jones reaches Dylan through "We Are the World" the same
year. So we deleted every crowded recording (15+ credited artists) from the graph and measured again.
Almost nothing happened. Miles–Dylan: still 1 recording (the Sun City single credits its stars in small, uncrowded groups). Quincy's distance histogram shifted by a rounding error; the reachable universe shrank by 0.2%. The session web is so redundant that no single wormhole matters: close one 1985 charity single and a thousand ordinary Tuesdays in the studio route around it. Small worlds are not built by grand gestures. They are built by session musicians.
Method: breadth-first search over shared credited/performed/produced recordings, shared written/composed works, and band co-memberships (39.6M recordings, 2.9M artists); artist-to-artist hops = bipartite distance ÷ 2. Counterfactual removes the 4,000-odd recordings with ≥15 credited artists. Computed August 2026 against the 2026-07-25 build.
