You don't have to be a member of the QI Club, in Turl Street, to view Johnny Dewe Mathews's recent paintings exhibited under the title Syncopated Rhythm. The exhibition, which sprawls up the stairs, into the club's dining room, library and bar is open to the public every afternoon until October 27.

Its opening conveniently coincides with the Oxford Chamber Music Festival which is taking place this weekend. This means those late-night jam sessions at the QI after the main concerts will happen against a backdrop of visual music, as the sensation of rhythm is ever-present in Johnny Dewe Mathews's paintings.

There is so much rhythm in his work that even subjects not related to music pulsate with vitality and spontaneity.

Many pictures depict musicians and dancers but there are kitchen studies, too, and works that highlight the warmth of the hot Brazilian sun as it pours on to tanned chocolate bodies dancing in the surf.

Perhaps the spontaneous nature of these pictures should be stressed, as each work suggests it has been created from snapshots of a thousand little gestures pinned on to a canvas at the speed of light. These are works that have been created by an artist whose admitted goal is to be inside the action of the image, looking for a line that tells its story.

The collection includes sketchbook drawings, watercolours, monotypes and oils.

Two kitchen drawings, hanging at the top of the main stairs allow us to see just how he uses one line to breathe life and movement into a character. His watercolour Chef's Kitchen, hanging close to the QI members' bar, gives us the finished version, which features a selection of those chefs in the sketches. This time they are ordered and in line - yet the movement and sense of urgency those overlapping pencil lines instilled is still there.

The exhibition runs until October 20 and will be open to the public every afternoon for its duration. Appointments to view can also be made through the Dadbrook Gallery on 01844 292459.
