Yeah, Tool at the Sziget Festival! I believe it to be good news for eastern/central european-fans:)
http://www.sziget.hu/festival_english/news/85944.html , they are simply described as "the most influential rock band of the last decade", but the hungarian text elaborates a bit more. I suppose its quite usual and understandable for festivals to announce that every band they feature is the very best of its genre, but makes the listing a bit ridiculous. Its funny that it happens to be the truth with Tool :)
As for Danny's troubles with recovering, I hope it really is just an april fool's joke. :-p
