Our operatic founder and vocal guru, Elizabeth Zharoff, has multiple degrees in music and voice from the Curtis Institute of Music, Oberlin Conservatory, and Berklee College of Music. She's also a voice science nerd. Mrs. Zharoff has performed in 18 languages, throughout major venues in Europe, Asia, and North America.

One video I particularly enjoyed was her reaction and analysis to Deep Purple's BBC live recording of Child in Time:
