I don't often get to listen to Villa-Lobos music I've never heard before. This is Aeanan, a vocalise, from the new CD by the Norwegian boys' choir Sølvguttene. I can't find any reference to this work in the Villa-Lobos repertoire; can anyone help? I love the bird calls!
One thing we know: Villa-Lobos knows his way around a vocalise!

Villa-Lobos used the same tune in building one of the pieces from his Cirandas. Here's Sonia Rubinsky playing this piece, from the first volume of her Complete Piano Works:
