Metallica have written on their website that they are to play this summer's Download.
They refer to the short tour they will be doing as "escape from the studio 06", the main priority for this year was to get the new album written and recorded, but they were apparently then asked to play some festivals.
In an interesting twist one of the other dates on the schedule is referred to as 'Download Ireland', scheduled for June 11th.
Metallica say they will be appearing at the main event on Saturday 10th June.
More names are expected later today (8th February).
Tickets are already on sale, with Prodigy, Bullet For My Valentine and Trivium already officially confirmed.
