Her "Lowlands" installation for the Turner Prize exhibition held each year at the Tate Britain gallery in London features only her voice singing old Scottish laments through a three-channel sound system. The work is based on a similar installation originally played underneath three bridges in Scotland as part of the Glasgow International festival of visual art.

Of the other three nominees for the prize, painter Dexter Dalwood has been installed as second favorite. His paintings for the Turner show tackle well known moments from recent history, including "Death of David Kelly."

The image of a tree against a moonlit sky is Dalwood's representation of the suicide of the British weapons expert who was found dead in 2003 after being named as the source of a BBC report that the British government had exaggerated the weapons of mass destruction case for going to war in Iraq.

Angela de la Cruz questions the definition of painting by taking her work into three dimensions by twisting and contorting the wooden frames to which her brightly colored canvases are attached. And London-based video artists The Otolith Group, comprising Kodwo Eshun and Anjalika Sagar, is preoccupied with reviving forgotten works of the past.
