I basically agree with Tony, but it's not quite a matter of "as much about X as about Y"; it's "as much about X as about anything else", and "anything else" means any other aspect of the jazz camp. "Camp" implies those who are committed to and defend a cause, so the "jazz camp" could mean all those who are keen on jazz; but here, "professional awareness" implies that it probably refers to the community of jazz practitioners: jazz musicians.

"As much about X as anything else" is a common expression; in fact it's a set phrase. It means that nothing else, no other element or feature of the thing concerned, is more important than X. X is what mainly characterises it. Strictly speaking it is not saying that X is more important than any other aspect, since it leaves open the possibility that something else is equally important (it doesn't say "more about X than anything else"); however, that, in practice, is what one understands it to mean.

So interpreting it a little further, you might say that it means something like: "No quality (or accomplishment) is more important to a jazz musician than professional global awareness".

Professional global awareness could mean an awareness of what everyone else in the profession is doing, or a complete awareness of what a jazz professional does.

By the way, I quite agree with Tony and Terry that in this expression X is often something unexpected. You might expect that the most important thing would be musical skill rather than "global awareness", for example.

But one reason I wouldn't express it as "as much about X as about Y" is that there's no single Y; Y could be anything, any aspect of the jazz world. There's no opposition between "jazz" and "professional global awareness"; the latter is one of many aspects of jazz.

Now that you have explained that this "jazz camp" is a kind of course of instruction, it probably means that as much time and attention are devoted to professional global awareness as to any other aspect of being a jazz musician (such as instrumental skill). There is no other aspect of being a jazz musician that receives more attention at the camp than this one.
