One of my favourite writers in Bristol at the moment is the Spanish artist Claro_que_sssnoh. His distinctive pieces are sometimes associated with his HMR crew and sometimes, like this one, as stand alone pieces.
Claro seems to particularly favour this spot for his solo work and at any one time there may be several of his pieces here of varying ages. What makes his work distinctive is that the letters are made up of a continuous line of script, like joined up writing, which is quite unusual in graffiti writing in my experience. Beautifully colourful and nicely finished, this is a fine piece from Claro.
