Brian Fallon of The Gaslight Anthem has posted an update to his blog revealing that he is, in fact, working on the "night time" music he mentioned in his blog. He had said this about it previously:

I would like to make a record people can listen to in the night time. I think I'd like to do that with a band name and some friends where we can dress like the Bad Seeds, in suits. Seriously.

So far, Brian has only confirmed the "night time" part, but has not picked a suit yet. Check out the blog here.
