Fronted by Eddie Vedder, Pearl Jam's albums include V, Ten and Backspacer
Rock band Pearl Jam have been announced as the headline act for 2010's Hard Rock Calling event 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.
Tickets go on sale this Friday from the event's official website.
Last ever show
Meanwhile, Emerson, Lake and Palmer and ZZ Top have been revealed as the headliners of a new UK festival dedicated exclusively to classic rock.
The veterans will play the High Voltage festival in London's Victoria Park on 24 and 25 July.
According to organisers, Emerson, Lake and Palmer are reforming especially for the event, playing their "one and only live performance of 2010 - and possibly the last show they will ever play together".
Comprising Keith Emerson (keyboards), Greg Lake (guitar, vocals) and Carl Palmer (drums), the group sold more than 40 million albums of progressive rock, with songs ranging from tales of environmental apocalypse to mechanical armadillos born in volcanoes.
They were persuaded to play by Classic Rock magazine, which is building the festival upon ideas from their readers - including designated hotels, "proper" beer and no booking fees.
Tickets for the two-day event are on sale now.
