I don't know, haven't been to a lot of slipknot shows, in fact this was my first one :) But from what I've seen on the internet they use fire/fireworks in concerts only as part of knotfest and other big festivals
@@caro7157 oh wow, sorry about the phobia. I can relate, you want to have fun, but it gets in the way. But anyway, I really appreciate the effort and the excellent show they give to fans in their concerts, apart from the music. I wish they could do such concert in my country (Israel) but unfortunately due to a lot of bureaucracy and restrictions, we can only fly abroad to experience such concerts with such effects and all.
