Query: Disappointed

This dvd is essentially an low-quality production of her performance at a regional fair. The video style and audio quality are marginal. Her performance, while pleasing, had none of the dynamic range I had come to expect. I'll wait for a more competent production from London. The dvd is disappointing, because she has so much talent and it's simply not present here.
