A rare feat indeed!
I was wondering how Bock got in on Gerald Wilson in such a big way at Pacific Jazz in 1960, and it wasn't reall him, apparently, it was Albert MArx, which makes sense.

Richard Bock, president of Pacific Jazz records, had a roster of some of the most prominent musicians in what had come to be called the West Coast Jazz movement. They included Gerry Mulligan, Chet Baker, Bud Shank and Bob Gordon. Bock did not have a big band on his label.
"I knew Dick Bock and had followed his work," Wilson told me. "The first time I approached him about recording, in 1953, was at a Billy Eckstine record date I was visiting. And there were other occasions through the '50s when I ran into him and brought it up. He explained that, for various reasons, it was hard to record a big band. But in 1960, he called me. He had set up a deal through Albert Marx to record me."
Wilson was under contract to Marx, the president of Discovery and Trend Records. Bock recorded the successful series of Gerald Wilson albums for Pacific Jazz, but Marx owned the records.
