Mark Greeley asked:

>Soloists or orchestral players?

Then added a list of soloists which included John Bruce Yeh.

Don't forget that JBY is also the assistant principal clarinetist of
the Chicago SO, sitting next to the formidable Mr. Combs.  It's quite
a section, among a number of remarkable sections in that orchestra.

DPHorn, a particular fan of the CSO cellos.
