Yelling is at the heart of Katz’s work as a performer and composer. Best known for her flute-guitar-vocals experiment Floom – the name is a portmanteau of “flute” and “doom” – she has leapt across the boundaries that divide classical, jazz and heavy metal. “God, I just feel like I’m so weird,” says Katz, who has an M.A. in critical and comparative studies in music from the University of Virginia. “Doing a metal set with flute…when people ask me, ‘What kind of music to you play?’ I get so boggled.”
