I don't tend to like live albums, probably because I have been to so many shows (including those I worked, I've seen literally hundreds). But I do like Pink Floyd's Pulse and Metallica's S&M. (Dis)honorable mention to Type O Negative's Origin of the Feces; it wasn't actually recorded at a venue and the crowd noise is simulated, but to the best of my knowledge it *is* a one-take performance.
