Aaaah, city living. A stack of newspapers is regularly dropped off in front of the door to the club, and Barry picked them up with both arms to move them out of the way.

They were soaking wet.

It has not rained in weeks.

The jury is still out on whether we're going to pour new concrete for the front wall; that's apparently a much bigger job than I thought. You were probably thinking, ``build a form; pour in concrete; done,'' right? Yeah, me too. Apparently ``pouring'' doesn't really describe the process. Since we're in earthquake country, the building codes say we have to have a closely-spaced grid of rebar inside the wall, deeply anchored into the existing pillars. So first that has to be drilled in, then the concrete is poured/slathered on around it, a foot at a time.

Apparently building a cinder-block wall isn't really an option, because that also has to have rebar inside of it, and if you're not building a wall from scratch, but rather, trying to fill in a hole in an existing wall, getting the bricks threaded over the rebar is a huge hassle, so that would end up being even more expensive.

Also, getting the permits for this kind of thing is also very time-consuming, due to the fact that it means putting a lot more weight on the wall, so they want to see proof that the building can handle it... So now we're exploring other soundproofing materials, to hopefully find something that is sufficient, and yet won't cost a fortune and take a month to install. It's hard to find numbers, like, what dB reduction does one get from N inches of concrete? From four layers of sheet-rock plus foam insulation?

1015 Folsom just built a new wall: they basically built a second concrete bunker that encloses the existing building. It looks pretty impressive, but they can do stuff like that because they're open and have a huge revenue stream, whereas I'm trying to figure out how to get my club open at all without going broke first. I really don't want to have to go get a real job, that would, like, suck.

A few friendly readers of this page sent me pointers to the materials that they had experience with in soundproofing shooting ranges and recording studios: www.silentsource.com and www.soundproofing.org. See, I'm not just talking to myself here! I love the net.
