After hearing the Black Beauty samples, I really can't understand why this sourced has been so critisiced. Sure, there are pitch variations in No Quarter and some annoying people chatting but, besides those nitpicks the whole source lets you hear the bands performance better than the known circulating recording. I can hear Jimmy's solos better on this one. And I can see (well, hear)why some Zeppelin experts like Paul Sheppard rates it even above the LA Millard tapes. Even the Ten Years Gone solo (an usually painful thing to hear on most 77 bootlegs) is pleasant. Only an out of tune bit that Jimmy hurrily solves. I also came late to the download link, and I would be very grateful if someone could send it to me. Thanks
