Neil Young has been confirmed as the Saturday (27 June) night headliner for this year's Hard Rock Calling.
The singer-songwriter, who will also perform at Glastonbury and Isle Of Wight Festival, is set to play the Hyde Park event alongside the Sunday (28 June) bill topper Bruce Springsteen.
Blues man Seasick Steve and the critically acclaimed Fleet Foxes are also set to perform on the Neil Young day along with Ben Harper And Relentless 7 and The Pretenders.
Speaking about their appearance, singer of The Pretenders, Chrissie Hynde said: "We would play a garden shed to be on a bill with Neil Young but Hyde Park – summer – with 'The Loner'. This is what makes a thousand hours on tour buses all worthwhile. This is why people get in bands."
Hard Rock Calling 2009 will take place at Hyde Park in London from 27-28 June.
Tickets for the Neil Young day will go on sale from this Friday (13 March), priced at £45.
All passes for the Bruce Springsteen day have sold out.
