This is just a few minutes of rapturous beauty. It's a group I've never heard of, but I hope I hear more of them. I first heard this piece on an LP called Pastorales in the 1960s - we played the grooves off it - and since then I've been trying to piece the album back together. This is the best version I've found of this lovely melancholy piece.
The group is Tempest Winds Chicago. More, more, I want more!
