Camille

Camille O' Sullivan is a superstar. Forget the fact that her name is not as instantly recognisable as some of the other artists performing at this year's festival. A concept as fickle as fame is wasted on a talent like Camille's. Her stardom is based on the often forgotten qualities upon which a performer should be judged; passion, conviction, presence, and crucially for a female solo singer, a large slice of glamour. O' Sullivan doesn't so much command the stage, as positively own it.

Half Irish, half French, O' Sullivan has inherited the theatrical flair of both. A popular fixture at the George Square garden's Spiegeltent since 2004, O' Sullivan has this year been upgraded to the Queen's Hall and its bespoke Georgian interiors make the perfect backdrop for her show.

At 10 pm sharp she struts on stage in black heels and a little black dress, every inch the provocative chanteuse, with her ruby red lips gleaming in the spot light. Stopping to cast the audience a smouldering look, her band launch unprompted into Jacques Brel's 'My Death', and for the next hour and a bit, the audience are captivated by her every move.

The songs she performs tonight are not what you might expect from a cabaret performer who is clearly enthralled by the nightclubs of Weimar Germany and works of Brel and Brecht, but are in perfect keeping with her 'Dark Angel' title. We are treated to darker numbers from the likes of Tom Waits and Nick Cave, alongside more playful tracks such as Kirsty McColl's 'In These Shoes'. Her choice of songs match her performance style: smoothly seductive one minute, excitedly childlike the next.

Make no mistake, this is no cheap parody. O' Sullivan more than makes these songs her own. She has carefully selected ditties that suit her cabaret style, and which work tremendously well in a big band setting. Bowie's glam rock classic 'Rock n' Roll Suicide' has never sounded so dramatic, so thrilling as it does tonight. Her band are flawless. Decked in matching black suits they complement her unique voice, and their bold rearrangements of well known tracks are pulled off with aplomb.

Great though the music is, it's O' Sullivan herself that makes this show something extraordinary. Playful and sexy during one number, achingly melancholic the next, her show flies by in the blink of an eye and, like all great talents, she leaves the crowd desperate for more. She takes a well deserved standing ovation with typical good grace, taking the time to thank each of her band, and then departs as dramatically as she arrived. A truly outstanding talent, O' Sullivan's show is nothing short of a sensation.
