The most excellent Nate McNeil put in a ton of work to help get these window coverings made. They seem to block a fair amount of the music - but they can't stop the low end. (Not even the cinderblock really stops that, of course.)
Huge kudos are also due to A Cassandra Utterance, who showed up and put in the winning shot by getting these painted up nicely. They're a way cool band, and way cool people. You should check them out.
With these puppies over the windows, I think we can push things until 9:00 PM pretty safely. (Nobody's complained to me about that yet, and I'm hoping that will stay the way it is...)
Oh yes, before I forget, another venue that seeks to get the locals some money for their efforts has opened. I think more venues are always a good thing - more venues means a community with more music! The new place is called Happy Time Music. If you can't get a show at Underground, I would consider trying to get your show there.
