Giorgio Griffa’s second solo exhibition at Galleria Lorcan O’Neill retraces the artist’s journey from the end of the 1960s onwards through a brief retrospective of works. From the radical rigour of the 70s to the more expressive and liberal gestures of Griffa’s contemporary pieces, the works come together in a vibrant sequence of colour and signs. As though stopping a thought midsentence, many of the artist’s works display a deliberately incomplete end-point in keeping with his belief that painting is “constant and never finished.”

Richard Long’s fifth solo exhibition at Galleria Lorcan O’Neill is dedicated to mud paintings, with a selection of works which date from 2005 up until the past two months. Long demonstrates his penchant for creating simple geometric forms endowed with rich personal significance, applying the mud of the River Avon, which flows through his hometown of Bristol, to paper, panels and walls with vigorous, fluid gestures, or with carefully placed fingerprints and handprints.
