Sorry I couldn't help more. But if you're gonna check this out because you like most of the bands No Sleep signs then I'm sure you'll enjoy it.
Edit: I tweeted at Grey asking what he would give for a RIYL and he said Superchunk, Sebadoh and Lemonheads if you're familiar with those bands (I'm not haha)
that's reeeeallly funny. I know Superchunk, Lemonheads by name only. I never trust artists with RIYL's because I think instead of telling you their sound-alikes, they'll end up just telling you their influences...which I don't always care to know. If music I like is too derivative of its influences, kinda kills the magic, hahaha. Super awesome that he replied to you though!! Super sweet.
