One of my favorite things in the Bay Area is “Instant Band Night,” where musicians randomly get assigned to be in a “band” together. They have 5 minutes to plan what to play, and then they immediately go on stage and play a 5 minute song. It is incredible and beautiful and vulnerable. I always have a blast.

You also have to come up with a band name, and a randomly selected band artist has 5 minutes (while you are performing) to draw the poster.
I try to do it as often as I can, but it is a bit of a jaunt by BART. This is the only (small) downside.
