Gillian Jagger has, during her long career, been a 'geologist of material'. Her use of direct plaster casting in some work, and manipulation of entire trees in recent installations, are an immediate statement of material force. Since 1985 Jagger has been bringing trees into her studio and highlighting the relationships that they portray to other things in nature. "I gut them. Polish them, arrange them and even paint them to bring out these repeating forms common to us all. How seldom we see in each other what we have in common with the formation of the tree," says Jagger.

Arnold Nadler and Lee Tribe are constructors in steel. Their supple and poetic shaping of this obdurate material manages to retain the angle and plate of the original stock. Nadler as the son of an immigrant tool and die maker, was trained at a very young age to look carefully at how things work, "to steal with his eyes" as his father put it, while poring over the shops and drafting tables of his practice. "Feats of engineering, both utilitarian and evolutionary, have always appealed to me. This plurality gives me momentum," says Nadler

"Lee Tribe is one of the few sculptors with roots in the abstract tradition of Julio Gonzalez, David Smith and Anthony Caro who has stuck to his guns and successfully forged a personal style with a contemporary feel", write Robert Taplin for Art in America Tribe forms massive agglomerations of smaller steel parts that are forced into a unity through careful fitting and intricate welding.

Cynthia Harper will create an organic inspired installation titled Beacons. Made up of curving wire, which the artist has smoothed and simplified. Created from the wood of trees near the artist's home, this piece is part of a series of works exploring the nature of the timber of different regions. Cynthia Harper is a constructor who derives inspiration and vision from the engineering of bridges and gantries. Her expression of heroic construction uses bolted timbers and joists in site installations that continue a sculptor's sensibility in the use of proportion and delicacy of movement.
