I saw Tullica only once, in 2012 on the Entire Black Album tour (which I could definitely live without; funnily enough, the only time I saw Peter Gabriel live he was doing the So album in its entirety, which I could also live without, apart from Red Rain, lol) and I must say that they were great. Yeah, Lars is Lars (and I don't think he deserves to be allowed to repeatedly fill his mouth with water and literally spit at the front row fans, that's just ... disgusting), but they were on fire, which they often seem to be, and they made even stuff like Struggle Within and Sheep Shit work for me.
Also, Gojira and Machine Head were playing before that, which was the first time I heard the former and they were absolutely great, it was my biggest discovery of the year... and the crowd that mainly came to hear Nothing Else Matters was booing and whistling. Machine Head had absolutely shitty sound and when Tullica came on, they actually also got some boos from .... the crowd that mainly came to hear Nothing Else Matters. Yeah.
