Hemper is simply an outstanding graffiti artist verging on genius in my view. He appears to have taken a liking to the tunnel in Boiling Wells Lane, which historically doesn’t get anything like the attention that St Werburghs tunnel receives only a couple of hundred meters away. It is a smaller tunnel and there is no lighting, which might account for the smaller turnover.

These gorgeous letters, spelling HEMS, appear to be bursting out from the wall and the purple void beyond. I love the way he has worked cracks into the background and some fallen bricks underneath his letters. The piece is so full of movement and depth – the work of an artist at the top of his game.
