Here's a live show with Black Flag from 1982. It's a soundboard recording so the quality is pretty good. Though a bit bass-heavy and occasionally slightly distorted, still, overall it's pretty good.
The set list contains mainly Slip it In/My War-material, but also a few of the older songs. Unfortunately I'm fairly certain the first track is missing, since the set begins with "Black Coffee" from the get go. Also the last track cuts off at the end.
Despite the flaws, this show is still worth checking out.

PS: Apparently a live show, also from 1982, was released two years ago, but as far as I can see, it's not added on discogs, so I'm unsure if it's legit or not.
