Lineup 2018 in Reading & Leeds Festivals Posted 3 hours ago · Report reply 2 minutes ago, Andre91 said: I didn't mean it as in they could play the shows Metallica play. I mean in terms of legendary metal bands, Sabbath, Maiden, Metallica, Slipknot. Slipknot have to be included in that as they are the biggest metal band of their generation. In the grand scheme of the history of heavy music and the biggest bands, Slipknot have to be grouped with those. They might be the biggest metal band of their generation but they're nowhere near those three in terms of legendary status. There has to be a cut-off somewhere.
