An ad for the new Massive Attack album has been banned by the London Underground authorities on the grounds that is looks too much like street art. The advert is for the Brtistol group latest CD “Heligoland” and was to have been displayed in “tube” (subway) stations throughout the British capital. But because the album’s cover art looks too much like the “graffiti” art of popular street artists such as Banksy, it has been deemed unacceptable. The art work in question was created by one of the band’s members, Robert “3D” Del Naja.
