thanks David...i guess that explains it. i do actually have that Nassau show....Brian, i just got that from you not too long ago (along with the rehearsal AND Zep stuff)....i haven't listened to the whole thing...the quality is not that great for an audience quality but i'll eat anything up from those earlier years. it's taken a long time for bootlegs (soundboards, for example) to surface from this period. i'm anxiously awaiting more....i wish a decent soundboard would surface from one of the '76 shows. i actually have one from Cleveland but it's several generations away from the master and the equalization is way off...it's got decent bass and but the 1-4khz level is way too high so i have to lower it all the way on my system and it's still too much. it's definately a soundboard though.
