I remembered that, in addition to their one-day tour to Korea, 30POSSE had popped up in some other news, and in looking for what that news was started playing through some live sets. Here’s a good one:
30POSSE actually looks different now; they held their live celebrating their third anniversary the other day, and in it unveiled a new member and tweak to their look:

Interestingly, that new member and updated look weren’t the things I thought I was looking for, either, and I still don’t really understand what they mean by “reborn,” but that’s okay. Maybe it’s just “we were fairly quiet since last summer but are now going to be busier” or something. That live set was pretty good!
