Was a frosh at Tigertown at this time; had grown into Zep with II first then I after but really was always partial to II even with the later commercial success of IV. Had really left Zep and was really more into prog rock but then when a friend of ours got us tickets for this and PG had just come out we ventured into the AC and was slightly high ( OK, really high) the aura of seeing Zep took control and when they started with R &R was such a garbled mix did not even sound like them until next few songs and SRTS finally brought us to reallity that the Zep was in the house ! Proceeded to blow us away with Ph. Gr. set (Kashmir was the thing), NQ, Rain Song, D & C, MD, many others of course STH, and encore WLL. Was probably the most powerful rock show had seen to that point besides ELP's BSS and JT's Ta a B shows and definitley left an impression all these years later!
