Extreme Performance Art - What's Your View?

The BBC reported last week that artist Nasser Azam is set to create art in blizzard conditions and temperatures of below -30C.

In this report they explain that Nasser had planned the trip after he returned from creating art in space.  The artist climbed 23,000 feet in a specially-modified plane to work on the piece while weightless.

A painting he completed in zero gravity sold for $332,500 (£223,000) at auction in New York.

Now Nasser wants to continue, "exploring the creative limits of working in an environment that is unfamiliar," and is setting off to Antarctica.

But when does "Performance Art" become less about the art and more about the performance?

Do the two naturaly sit side by side or can one out way the other?

And is art that is created in such "Extreme" conditions really worth more in terms of money, then say a painting created in an artists studio?
