I saw Motörhead on Ace Of Spades tour but round about that time health and safety started to monitor the noise and capped it . It was a proud boast that they had beaten the previous nights noise record. I think it was over 130 dbs at the Manchester gig . A testament to this was most of my mates were half deaf at school the following day. The loudest gig I can remember was Ted Nugent on Scream Dream tour it was ridiculously loud.
