I'll agree with this, and add a few comments:
Eyes had the extended '74 coda (Stronger than Dirt?). Dark Star went places! Drums / Space sounded techno-y to start, stayed very electronic but got very weird. We were right behind the soundboard. The outdoor sound was loud, pristine, and had amazing stereo effects.
Hot day, very comfortable evening in the tree-lined bowl. Supposed half-capacity sold (~2,000?), made it quite spacious, but double that and it might be a different story. What a great time!
