Dear Sir / Madame
I’m writing in connection with a article “Sonisphere” 5/2010 to discuss my disagreed.
In that article you wrote very bad about The Sonisphere festival in UK. I’m of totally different opinion about it, because the concert was awesome. There were a lot of great bands like a Rammstein, Iron Maiden or Slayer, and a lot of audience. Rammstein gave the most spectacular live rock show ever staged. There were a flames, sparkles, fog and much more effects. The crowd were very impulsive and made a beautiful pogo, and very good wall of death.
Despite the fact that the water were very expensive and a security were very sensitive, it was the best concert in my life.
In conclusion I think that the article is very biased. And should be more objective.

Your faithfully,
