Sorry sarra, should have explained. Here's a usage example from a job ad:
"The ideal candidate will have marketing experience and a knowledge of symphony product."
And another, made up but not atypical, verbal example:
"We need to make sure our marketing is positioning symphony product in a way that will appeal to STBs (single ticket buyers) as well as subscribers."
What seems to be wanted in the first instance is knowledge of orchestral (or symphonic) repertoire and classical music artists.
And in the second instance it's just a bizarre way of referring to live orchestral concerts.
In both cases it's an attempt to force a performing art form into the jargon of the marketing profession, perhaps in an attempt to appeal to other marketers (but not necessarily music lovers). It makes me cringe and I rail against its use, with some success. ;-)
It is wonderfully cathartic and pleasurable, therefore, to observe fellow Wordies simply take the phrase and have fun with it in their own way!
