Actually (but coincidentally), the Don Carlo with Troyanos has just been released on DVD in a Big Giant Box of opera DVDs to mark James Levine's 40 years with the company. None of them has appeared on homevideo before, and a couple (an Ariadne with Voigt and Dessay, a Wozzeck) were known to have been taped but never were telecast at all. I'm also happy about the Rosenkavalier with Troyanos, Te Kanawa, and Blegen. For a Troyanos-lover like me, it's a feast.

(I'm actually happy about the whole thing. I bought it. And the matching CD set too, of selected Levine-led radio broadcasts over the years.)
