Tomorrow, at approximately 6 pm (not sure how exact that is; I'll probably start listening at like 5:30) California time, Nessa's going to be on 107.9 (Sacramento-based radio station). Apparently, they're giving out tickets to go see it later tonight; I'll see if I can get one, though it's not likely.
Unfortunately, the End doesn't stream their broadcasts (at least to my knowledge), so if anyone else in the Northern California area wants to try and record it, that would be great (although I might be able to as well, barring the miraculous situation in which I might actually end up going).
