Not seen this mentioned here yet but Offset festival have announced first artits playing. Copy and Pasted from thier site:

Over the years we’ve had some very exciting artists through our gates but this could potentially be the most exciting influential band Offset has announced yet! For Offset 2010 we’re pleased to be flying Liquid Liquid over from New York for what will be – amazingly – only their second-ever appearance in England.

These New Puritans join the helm for a very special live performance, having produced this year’s most groundbreaking album, plus Telepathe will be flying in from Brooklyn for a late night dancefloor-friendly live set.

Legendary Krautrock group (and Eno collaborators) Cluster make a very rare live performance, alongside pioneering cold wave band Charles De Goal, who will be preceded by a special Angular Records cold wave showcase. And, fresh from producing their eagerly-awaited second album with Diplo, Rolo Tomassi are set to return to our hardcore stage for their second Offset performance.

After one of the most jaw dropping performances of Offset 2009, Sub Pop signing Male Bonding will be moving up to main stage this year, along with Bo Ningen, a band whose hair-raising antics at last year’s event were hailed by the Observer as their best discovery of the weekend. Plus Factory Floor, O.Children, Invasion, Electricity in our Homes and more!
