I am to young to say first hand, but I have a few books on the wall, in that period it was the greatest concert experience on the road. This is outlined well in a GD gear book I have, some argue that Pink Floyd was the better concert experience, but they always say its because of the theatrics that PF brought to the stage during tours like Animals and DSOTM, the GD brought nothing but a mind blowing jazzed-out audio experience like no other. Audiophiles who also were concert goers swore that the dead tour of '73-'74 was buy far the best sounding concerts of the era, and I think the drugs made up for the lack of theatrics.
