i think it was yes. Im sure burton had a skeleton t shirt on ?. It sounded like and a few confirmed he was miming the clean parts.
its a shame as i saw them there supporting Slayer for a metal hammer show in 97 and they absolutely tore the place apart. its a real pity hows burtons vocals worsened over the years as like you i love fear factory
fear factory brixton 98 - burton was clearly miming
cradle of filth LA2 97 (i think) was so bad i actually laughed. was such a mish mash as if every member was playing a different song
machine head brixton 2001 - robb flynn was trying so hard to be hip hop it was utter cringe
metallica twickenham 2019- was in the middle of james relapse and the whole thing was a dialled in mess. while i sympathise with peoples struggles it was £100 a ticket
ive only got one bass now, no rig or anything but i wont get rid.................................................just in case
keep a bass, it wont hurt
