"The Stammerer" by Karl Kramer, featuring Peter Stewart and SONYC (String Orchestra of NYC).
In this piece, he sings of his devotion and the meaning of the contemplative life. Then, he tries to engage with the secular world, and is completely undone by a crippling (and virtuosic) stutter. The text for the stutter is simply the title of his biography of Charlemagne. After two heroic attempts, he sits back down and returns to his life of contemplation.
