Four controversial artists shortlisted for the prestigious Turner Prize for modern art will find out who has won later.
The bookies' favourite to receive the £25,000 prize from actor Jude Law at Tate Britain is Paul Noble who has spent 15 years drawing an imaginary city.
The Londoner's detailed drawings are of fictional Nobson Newtown, a partially ruined city, where the inhabitants are living excrement who, in some scenes, engage in orgies.
His work has been described as a parody of an ideal city.
Also shortlisted are Spartacus Chetwynd, Luke Fowler and Elizabeth Price.
Performance artist Chetwynd, who "lives and works in a nudist colony in south London", changed her name from Lali on her 33rd birthday "to remind people they have a choice in life".
She has said: "Like my art, my name-change annoys people. The moment it stops annoying people, I will rename myself again."
Chetwynd puts on puppet performances with a group of friends and family using her own handmade costumes and sets.
The artist, whose mother is a film production designer who won an Oscar for Howards End, always participates in her productions, wearing just a bikini for a performance called An Evening With Jabba The Hutt.
Her other work includes a week-long performance The Walk To Dover, in which she and her troupe dressed as Victorian street urchins.
Fowler, from Glasgow, is shortlisted for his film exploring the life and work of Scottish psychiatrist RD Laing.
Price, from London, is in the running for the contemporary art prize for a trilogy of video installations.
The £40,000 Turner Prize sees £25,000 go to the winner and £5,000 each for the other shortlisted artists.
Established in 1984, the prize is awarded to British artists under 50 for an outstanding exhibition or other presentation of their work in the 12 months before April 24 of this year.
Tate Britain director Penelope Curtis, chair of the jury, said: "None of these works are something that you can get in a few minutes. You have to spend an hour or two to get it, whether it's film, drawing or performance."
Judges say there is a "humanity" running through all the artists' work.
They hailed Noble's art as "a compelling life project" of "incredible, monumental graphite drawings".
They describe Chetwynd, whose recent exhibition Odd Man Out 2011 took the form of a five-hour play, as a "very interesting character" who involves the audience in her work.
Fowler, best known for his film portraits of public figures, is said to have an "autobiographical and biographical thread to his work".
Price started to make films four years ago and has a musical background, co-founding indie-pop outfit Talulah Gosh. Judges praise her "powerful body of work over the last three years".
Her work includes West Hinder, inspired by the sinking of a ship in 2002 with a cargo of luxury cars, and The Woolworths Choir which features degraded footage of girl groups.
Bookmakers William Hill make Noble the 11/8 favourite, followed by Price at 2/1, Chetwynd at 11/4 and Fowler at 5/1. Other bookmakers also make Noble the favourite to win.
