What a ridiculous story.

The only facts are that during an encore Pearl Jam made some comments, they smashed a mask, some booing was heard, and then at least 24 walked out.

Pearl Jam plays huge halls, many 15K or more. If a dozen dozen left, that would be less than 1%.

They are playing their encore, so the show was nearly over. None of the people exiting at that time were just trying to beat the rush?

When I see a band and they say "one more song and we're done", I boo loudly too.
