That Car Lot's Alive ... with the Sound of Music!
What ho: an outdoor campaign that (arguably) improves the landscape. The Calcutta School of Music encourages onlookers to "Learn to Appreciate" Mozart, Haydn or Bach on ads attached to posts, which are attached to telephone wires, which were strung up with notes, like sheets of music.
Would have been nice to see some random dude try playing them.
