If you thought you recognised that image as the artwork for U2's forthcoming album, "No Line On The Horizon," think again. It is in fact the cover of a 2006 album by American minimalist musicians Taylor Deupree and Richard Chartier, entitled Specification.Fifteen.

NME reports that Mr. Deupree has made a post on 12kblog accusing the world's biggest rock band of copying the cover. In the "rant" Deupree condemns U2 for not conducting proper research as both covers are based on a photograph by Japanese artist Hiroshi Sugimoto.

Deupree has said he won't be taking legal action, so really, after their appearance at Obama's Inauguration Celebration on Saturday and the enormous success of their new single "Get On Your Boots" on worldwide radio and online yesterday, he has just offered yet more free (although hardly necessary) publicity to Bono & Co. in the run up to the release.
