Got a lot of likely choices... Friends Again has a single vibe, but Wonderful is by far the most played and Out of My System, from the description, seems to fit the profile as well. And maybe they're just aching to put Holdin' on to Black Metal out... ;)
Askin myself this very question daily. My guess is that it won't be Circuital
I'm good with whatever the band decides our ears should hear first, just as long as its on vinyl.
