Alice Cooper sits at the top of Pink Floyd's similarity graph at 0.85, but the more revealing structural fact is that the top 10 splits cleanly into two clusters: a dense pack of classic and hard rock musicians, and a secondary band of actors — a cross-kind presence that is unusual for a band's nearest neighbors.

The shape is two-peak. The first cluster runs from Alice Cooper (0.85) through Paul Stanley (0.83), Steven Tyler (0.83), Bon Jovi (0.83), and Gene Simmons (0.83) — all Musicians and Bands, all drawn from the classic and arena rock world. Black Sabbath (0.83) and Tommy Lee (0.81) extend that cluster further, with KISS (0.78) and Aerosmith (0.77) rounding out the bottom of the ten. That accounts for nine of the ten neighbors — all Musicians and Bands.

The second peak is a single entry: Katey Sagal (0.83), an Actor, whose audience shape lands squarely inside the rock musician cluster rather than among other actors. Her score is nearly identical to the tightest musician neighbors, which makes her presence the structural outlier — not a stray low-score entry but a genuine second signal embedded at the top of the range.

The overall picture is an audience defined almost entirely by classic and hard rock fandom, with one actor whose followers map onto that same demographic profile with striking precision.
