Nice read, thanks for posting, though there are a few errors. The Wall wasn’t 100 feet high, and 100 feet is a LOT more than three stories. The tallest column of speakers was 32 feet. (It was for Phil’s E string and was able to produce the full low E wave crest to crest.) And the story left out the 3-night stand, February 22-24, at Winterland where the Wall performed wonderfully. Also, the official unveiling, the “Sound Test” on March 23,1974, was at the Cow Palace, not at “tspeaker feedbackly”.
