Are you a fan of his music? Do you have a favorite piece? I'd love to hear your thoughts.
I first heard his music in high school, when a teacher played a recording of Black Angels for us in music theory class. I then saw Crumb perform Mundis Canis [Dog's World] with David Starobin. I've since heard many more of his pieces (including the excellent Ancient Voices of Children, Vox Balanae, and Night of the Four Moons).
I love the sound of his music, his use of space, and the sense of wonder, mystery, and beauty that his music evokes for me.
So, to George Crumb -- thank you for all the wonderful music, and best wishes from West Virginia for a happy birthday!
* Addition: University of Missouri, Kansas City is celebrating the occasion in style, with a George Crumb 80th Birthday Festival.
