The second night of Neurosis’s two-day residence at the Brooklyn Masonic Temple is sold out, but if you skitter around like mad you might be able to get a ticket for the 24th. They’re here for the time being. And just to sprinkle a touch of panic over your scramble, the openers for both nights are US Christmas and a little southern metal outfit called Mastodon. If this doesn’t end up being one of the heaviest shows of the year, then we are very, very psyched about 2008.
