Might be a bad PA mix or something. Theres a lot that can go wrong, even with a great band. I worked as a stage roadie for a bunch of years in the 1990s and holy fuck was it a shitshow 24/7 in that game. So many moving parts, so many drunken rock and roll people. Things get chaotic and then things go wrong. Its part of the fun really.
by 1984 the NWOBHM had already proven that Venom were a very low tier band, sure they are extremely influential and cult, but they were heavily criticized back in these days for their lack of musicianship
