Nice review, man. Checking them out now, might buy this. Seems like something I need to hear. The Streetlight RIYL gets me excited too.
Edit: Yeah, listened to a couple songs and the Streetlight similarity is definitely there. It's in his voice the most I think. Really digging the horns, too. Better than most ska groups I've heard recently.
I haven't heard much Streetlight, but from what I remember I think they're a little more experimental? I could be wrong. The Closers are more straightforward, LTJ-esque. Not that one is better than the other - just observing.
