So I just called the Jam House about the gig on February 24th, and apparently nothing is actually confirmed on their end. I don't know what that's about.
The woman knew what I was talking about, though -- I'm guessing other people have asked about it already -- and she took my name and number, so hopefully someone will call me back when actual information is available.
Failing that, I plan to turn up on the door anyway and be like "heyyy so where's my good friend Brian~"
Just thought I'd let y'all know.
