The Empire Revue is a sort of variety/cabaret show organized by Keith Munslow, with a bunch of short musical and comedy acts. It's the first Sunday of every month starting at 8 pm and ending usually after an hour and a half or so. I went for the first time a couple of months ago and really enjoyed it, so I recommend checking it out sometime, even if you can't make it this time!
Chris Monti played in it last month and said that it was a lot of fun, so I'm really looking forward to it. I'll play one song; I haven't totally decided which one yet.
