Audience recording.
From the Uploader: I am pretty sure Doug taped this one. I think I hear him heckling the band at times. Pretty much all Venom recordings from this tour sound terrible due to the stage volume that they were pushing along with 1980s sound systems trying to keep up... but this one sounds better than most. Not sure why Slayer is incomplete (22 minutes), but this is all that was on the tape.
