I just got through watching Pink Floyd:Pulse. It was stunning... I'll have to put it on my list to purchase it was that good! I can definitely see popping it in the DVD just for the tunes, but the experience was pure eye (and aural) candy.
Never been a real big Pink Floyd fan, but when searching Netflix for some concert videos, I noticed that this one pretty much had the highest rating of them all. So, on a whim I rented it and it was definitely worth it.
Check it out if you get the chance...
