At first I thought maybe you were confused with Webern, but Good Lord, you are right! It is in a very tasty looking box of live performances released by the Cleveland orchestra in 2001.
Supposedly it was available from the orchestra website, but I can't see anything for sale there. I can't see it on Amazon. It's probably long out of print.
