According to their Facebook page:

they played at least 2 shows in August, including this:

and their most recent update reads:
'We'll be releasing the vinyl as a limited edition of either 50 or 100. The art is going to be all lino-cuts, in sets of 10. So, how do you get it? They'll be available at a gallery this March at SXSW in Austin, TX. We'll also play a short set. We want to do another event in another city, but we're still planning that. Dates and locations to follow.'

I'm both excited and confused.
