On of the first major collections of 21st century American Art Songs has been released by North Star Music. The brainchild of Robert Peavler, the collection includes the work of 90 living composers. Of special note is Volume 1 (S/A/T/B) for singers 16-21. Almost all of the songs in the collection are unique--in other words, what's found in the tenor collection isn't simply transposed into the soprano collection.
While working on a class for singers at Savannah Voice Festival, I interviewed Robert on zoom. An excerpt is being used in the class; the entire interview is here.
Look at this list of composers!
