Best Live Recordings:Performance and recording

I tend to like "live" recordings if done right...but these are often hit and miss...any suggestions?...open to all genres...for those fans of Portishead...live in NYC is a great show and an excellent recording to boot...also...Live at Leeds is considered by many to be the ultimate live rock recording...however...I was not that impressed with the latest remaster...somebody mentioned BB king live at the Regal on another post...is this really that good?
