On a walk down to the waterfront at Warsash, from the opposite direction to the route I normally take I noticed this music graffiti on the derelict base of the building on the point. It is remarkably sublte, if you look loosely you will see that they are individual notes in what appears to be a scrawl between old microphone and stencil tag.
It was also positioned at the base of the wall so the mic is growing out of the grass.
The flickr photo is geotagged too with the exact location, if you happen to be walking there before someone scrawls all over it.
It is carrying the Undenk tag too a sort of open source graffiti movement.
