Gotta love the one from the following night (4/26/71) with Duane all over it. The BIODTL too!
Some of my faves are from the early 80s, like 6/28/83, 10/10/82, 2/27/81....real uptempo scorchers, with plenty of Phil ordinance. A personal fave that I attended might be 7/2/87- I got to about 40 ft in front of Bob during post-Space and as they finally got to the big pause, some dude lit a string of firecrackers timed perfectly to the transition into SSDD. Excellent effect!
