I bought a bootleg in Germany years ago on a School trip of their Rock in Rio 2001 set, absolutely amazing show, setlist was incredible as was the quality as it was a radio broadcast.
Saw them at Brixton Academy in London years ago while I was at uni. Was disappointed they did nearly all of their new album but hardly any of the stuff i wanted to hear, last 20 minutes were excellent though haha.
I haven't listened to them for years though, still have the albums. Would be tempted to go see them again if they were doing perhaps a greatest hits tour or something.
