Is Metallica one of the best bands ever?

[Villavic]

So Metallica is coming to Lima for a concert in january. Today it started the ticket sales, and they hit the record: 12000 tickets sold the first day, exceeding the record made by Soda Stereo, the best (argentine) rock band in spanish language.

I'm really surprised Metallica produces those expectations. I thought about the Stones, Madonna, U2, MJ if he still were alive. Maybe it's because I'm not into metal, but I didn't know that a lot of people is, even in Peru.
