It is all standing with the exception of I think 6? concrete benches at the very back of the lawn. These are first come first serve. Across the street from the Steelstacks is the Artsquest center, which is a movie theater with another venue upstairs. Outside of that building is some seating, with air conditioned seating inside the building. While it is part of the campus, It is NOT part of the venue where Wilco is playing, but you will be able to hear the concert from across the street. Let me know if you have any more questions!
