I heard about this concert shortly tickets went on sale in America. It was a limited 1500 seater concert and from watching the extra bonuses on the BD you can tell a lot of work was involved putting this show together.
If you like all of Beyonce hit songs like "Single ladies", "If i were a boy" or "irreplaceable" then you'll like the acoustic remix of these songs. Beyonce decided to tone the performance down so no distracting dancers, no gleaming costumes or fancy light show (there were some) none of that. The concert is closet to 160mins so its well worth a night in to hear all of your favorite songs.
If you got the hardware to pump the tunes out then I suggest you do. It only have TrueHD 5.1 sound and not DTS but her vocals are strong enough to put you right in the front see of this amazing concert.
Highly recommended if you like her music and loved her other performance "Beyonce - the live experience"
