Undermine - Live Summer 1992 Riot Show

I have no details on this show. I didn't record it, and I'm not real sure as to how I came into possession of this show in video. I had this written down as "Riot Show" and I've long since forgotten why. Doesn't seem to be any riots going on during this show. I don't think Riot Skate Park was open back then either.
Per Micha Mills via the comments this was recorded in the summer of 1992. Title updated accordingly.
If anyone has any further info on this show, please let me know so I can update the info on this.
