A beautiful graceful and kind performer. The older adults loved her. Perhaps in terms of a birthday party, the music was too mellow for some. Some were upset that others talked and made noise during the performance which was really like a concert. Katherine is really wonderful. If you book her, make sure the environment is quiet and conducive to listening. I will definitely offer her more work, and will work myself to put her, next time, in a quieter space, so that everyone who comes can get the full benefit of her talents!
