UPDATE: New photo for the vanguard but I like my original write up so I'll be keeping it
I discovered there's really strange acoustics in the SW stairwell of the Urban Building. While working on the "look up see green" patio I used to descend this corrugated metal staircase and couldn't help but notice the noises. A booming bass from the flat parts and tinkering staccatos when my backpack straps swung and hit the railing. They would echo off the cement, if you stomped just right it sounded like thunder. Sometimes I find excuses to go down the stairs and pretend it's music. Here's a little video but it's not quite the same.
