I've put up my recording of Cloud Nothings at the Ding Dong Lounge (I'm still a bit bitter about the DJ). Unfortunately, it wasn't a great recording and the singer's voice took a few songs to warm up. This short radio set has none of those problems, although it's still clear that this is a loud band. I'm not really a fan of their first album, but their most recent album - Attack on Memory (which is where all these songs are from) is a stunner. Hopefully they'll make it back for one of the early '14 festivals.
This is a short live set broadcast a few months later. There's obviously a bit of overlap between the two, but I'd still recommend getting both, and obviously it's a no brainer if you're already a fan of the band.
