Rock band Pearl Jam have been announced as the headline act for 2010's Hard Rock Callingevent in London.
The Seattle group, who came to attention at the peak of grunge, have gone on to establish themselves as a durable act in the Led Zeppelin mould.
Best known for early hits Jeremy and Alive, they have also backed Neil Young on his Mirror Ball album.
They play Hyde Park on 25 June with the rest of the three-day Hard Rock Calling bill to be revealed later.
Pearl Jam Tickets go on sale this Friday from the event's official website.
