We are very said to announce that Chris Cornell had to cancell his appearance at this year's Metal Hammer Festival. Following statement was posted on the official Cornell's site earlier today:

"Upon completion of the U.S. summer tour, Chris was diagnosed with strained vocal chords and the doctor strongly advised that he take 10 days to two weeks off from singing onstage to prevent injury. Chris deeply regrets any disappointment this may cause his fans in Poland, Hungary, and Austria, and promises to come back as soon as he can."

We are very sorry for this situation and can only promise that other bands will play longer sets.
