The Blu-ray Video resolution is fine, it's not a killer picture, but it's still very good.
The quality of the Audio is better, again not a giant true killer, but vey much satisfying.
What truly shines, is the energy of the musicians from the band, the excellent performance on guitar from Jeff, the performance by the two girls singers, and the aura, the spirit from the audience. It's that magic communication between active (musicians) and less active artists (listeners from the audience) that is the true esssence.
Also the place, that Theater where it was recorded is a very cool place.
Overall: Pure Synergism from one of the greatest. A synoptic synapse of a synopsis.
