Tenacious D, the greatest band in the world (created by actors Kyle Gass and Jack Black), will precede their appearance at this year's Download shebang with the release of their third album.

'Rize of the Fenix', the follow-up to 2006's 'The Pick of Destiny', will be released in May.

They have also announced their first American show of the year, at Sasquatch Festival in Washington over the weekend of May 25-28. Jack White, Bon Iver and Beck also play the US event.
