Alguien sabe algo? lo he encontrado de casualidad, y la web siemplemente tiene una cuenta atras:
http://www.sonispherefestivals.com/
We were having a look on last.fm and they’ve got an event with Metallica and Linkin Park headlining with Lamb Of God and Mastodon playing too. It is called Sonisphere and there’s only a bloody website link as well!
