Slayer Announce European Festival Dates

As if the legendary re-pairing of Slayer and Megadeth for the upcoming American Carnage tour wasn't enough, the new year will bring yet another killer concert lineup for thrash masters Slayer when they join Metallica, Anthrax and Mastodon at Sonisphere 2010 in Poland next summer. Marking the band's return to the European festival circuit, Slayer will also make an appearance at Sonisphere Knebworth in 2010 -- a three-day U.K. festival set to feature Iron Maiden, Rammstein, Anthrax, the Cult and much more.

Supporting their widely received November release 'World Painted Blood,' Slayer's 11th studio album debuted at an impressive 12 on the Billboard 200, and the track 'Hate Worldwide' has been nominated for a Grammy Award in the Best Metal Performance category -- a title they've won for the last two years.

As another huge decade for Slayer comes to an end, their camp promise more European festival dates to be announced soon. The two aforementioned monsterous dates so far are June 16 in Warsaw, Poland and Aug. 1 in Knebworth, U.K. respectively.
