The Rolling Stones are releasing “100 unique copies” of the 1971 song “Dead Flowers.” The seven-inch singles are part of the Secret 7-inch charity campaign, in which artists release singles in one-of-a-kind sleeves with the proceeds going to Nordoff Robbins, which provides music therapy and music services to handicapped and ill children.

The Stones and six other artists – Peter Gabriel, Diana Ross & The Supremes, The Chemical Brothers, St. Vincent, The Underworld and The Maccabees — are asking the public to “interpret the tracks” and design a sleeve in their own style for every seven-inch. 700 sleeves will then be exhibited in London before being sold for $75-dollars each.
