An 11-year tradition. Four important artists. One unassuming title. Go to the Vangard Gallery expecting its Christmas show to have a collection of safe, comfortable artwork to give as a present and you may be disappointed.

The presence of Patrick Graham's mixed-media paintings from the Odalisque series are a case in point, as his depiction of human form as a weak and vulnerable entity is as disturbing as it is captivating. Graham has that rare talent for skilfully rendering form and space without being seduced by mere facility and showmanship. Instead, we see the physicality and presence of his subjects in their brutal, raw state - expressed with an intuitive understanding of media and surface.

Patrick Hall is the obvious companion to Graham in this selection, as there are some basic similarities in terms of media used. But Hall's flower and bird imagery is far less confrontational. That said, his artwork is far from tractable, as the artist imbues these humble sources with obvious character and presence - so much so that they suggest icons or relics of great importance.

There is a tidy flip side to the expressionist predilection of the other two: cool, elegant minimalism. Chung Eun Mo's paintings are the epitome, with their ordered interlocking shapes and flat, austere colouring.

Michael Warren's sculptures are the most discrete of all, and are an interesting counterpoise to the turbulence of Graham's paintings. His forms are deceptively simple, as these upright totemic lengths of wood alter from true vertical towards the base, subtly distorting our perception.
