Ween have had to withdraw from the second of the two All Tomorrows Parties weekends next may after they had to cancel due to personal reasons.

Ween's first choice of acts was Dinosaur Jr and they have agreed to step up to the curatorial chair in their place.

If you have bought tickets to Weekend Two on the understanding Ween was curating and wish to receive a refund, you have to contact your point of purchase by Thursday 5th January.

Alternatively, you are also able to exchange your tickets to Weekend One until this same date or as long as they are available.

Weekend One takes place from Friday 12th to Sunday 14th May, and is curated by Mudhoney, the Yeah Yeah Yeahs and Devendra Banhart. They'll be joined over the weekend by:

Black Mountain, The Scientists, The Drones, Country Teasers, Comets on Fire, David Dondero, TV on The Radio, Ex-Models, Celebration, Blood Brothers, The Liars, Imaginary Folk, Tall Boys, Espers, Vetiver, Bat for Lashes, The Metallic Falcons, and Jana Hunter.

Weekend Two takes place from Friday 19th to Sunday 21st May, and is now curated by Dinosaur Jr, Sleater Kinney and The Shins. Already confirmed as joining them are:

New Pornographers, The Gossip, and David Cross (MC).

Both events will be held at ATP's normal site of Camber Sands on the Kent coast, with accommodation in self-catering chalets for groups of 4, 5, 6, 7, or 8.

Tickets are on sale for both events, priced at £125 per person.
