Morning listening: Tchaikowsky and Piazzola on APM's Performance Today

I take Astor Piazzola's work very much on a composition by composition basis.... some of it leaves me relatively unmoved, other pieces I really enjoy.  I really enjoyed the Tangata for saxophone quartet, played by the Ancia Saxophone Quartet at Bethlehem Lutheran Church in Minneapolis, Minnesota.  21'30 in this feed from Performance Today (you'll need to click on Hour 2 on the RHS of the page; stream should be available for at least a week).  I thought it might be Poulenc, then changed my mind to Piazzola, which turned out to be right.  It's probably the Poulencian playfulness and part-writing that grabbed me, as well as the superb playing by the quartet.  Following it (at 34:47  in the same feed) Tschaikowsky's dramatic overture-fantasia on Hamlet, Opus 67, is also extraordinarily well-played and recorded from a concert in Hamburg, by the North German Radio Symphony Orchestra, under Christoph Eschenbach.  Excellent, dramatic stuff.
