Bill Curbishley
The Who · Robert Plant · Jimmy Page · Judas Priest
Bill Curbishley has managed The Who since 1976 through Trinifold, the company he founded in 1974, and is the manager who talked Robert Plant into dissolving his band and starting over — and later talked him back into a room with Jimmy Page.
“When you sign an artist, you're taking their life in your hands. You have to commit 100%.”
Curbishley took over The Who in 1976 after a royalty dispute, and has been there ever since — roughly half a century with one band, which in this business is less a job than a geological era. Trinifold, founded in 1974 with his wife Jackie, grew from that one client to Judas Priest, Robert Plant and Jimmy Page.
The Plant story is the one worth studying. In the mid-1980s Plant had a working touring band and a solo career that functioned. Curbishley told him to disband it, start again with new musicians, and write with different people. That is an unusually expensive piece of advice to give a client who is currently paying you a percentage of the thing you're asking him to destroy, and it is the reason Plant re-emerged rather than settling into a long, comfortable decline. In 1994 Curbishley took on Jimmy Page as well and got Plant and Page working together again — the 'Unledded' album and tour — after other people had failed at the same errand for years.
He has been consistently blunt in interviews about what the job is: signing an artist means taking their life in your hands, and it demands total commitment. He has also been blunt about the bullying of artists that was routine in the industry he came up in, and about his dislike of it.
Kill the format that plateaued
Find the thing that got you here and has now been flat for two quarters — the series, the sound, the format — and end it deliberately instead of milking it down to nothing. Curbishley told Robert Plant to disband a working band. The tell is when engagement holds steady while reach stops growing: that's a ceiling, not a plateau, and no amount of posting fixes it.
Be willing to tell your client to burn a working thing
A manager on commission has a structural incentive to protect whatever currently generates income. The managers who last are the ones who will tell an artist to dismantle a functioning career because the next version is better — and who are trusted enough to be believed when they do.
