Tracey Emin's 'A Moment Without You' comprises five sculpted bronze birds positioned on top of a series of high poles. For Emin, the diminutive life-sized forms serve as symbols of hope, faith and spirituality: 'I've always had the idea that birds are angels of this earth and that they represent freedom'. Emin has noted: 'Most public sculptures are a symbol of power which I find oppressive and dark … I wanted something that had a magic and an alchemy, something which would appear and disappear and not dominate'. There is a poignancy in the elevation of these small creatures, physically and metaphorically, as they benignly watch the world below. Regarded as one of the world's most significant contemporary artists, Tracey Emin's art is primarily expressionistic, a cypher for memories and emotions that can be frank and poetic, intimate and universal.
