I'm wondering how rare flute choirs really are and this come across my computer. Check out the Flute Choir of Atlanta. It looks like many of the performers play more than one flute. :ugeek:
i found a couple of things composed for flute quartets
you can see/hear them at: http://www.flutetunes.com/tunes.php?instr=4
i don't like the first one, but the second one is o.k
flutetunes.com is where i get most of my sheet music.
