Saw King Crimson and the Zappa Band a few weeks ago and the The Black Crowes last week. Both at The Concord Pavilion in Concord, CA. Outdoor venue. Concessions were open. Lots of people but it was nice to be out listening to music. People in the lawn all respected each others space. Was kind of easy to do because it was not sold out.
I'm going to Phish at Shoreline on Wednesday, possibly a different situation with a lot more people.
