Ireland's Sinead Mulvey and Black Daisy will rock on to the Eurovision stage tonight in the hope of clinching a place in Saturday's final.
The young girl band is pitted against 18 other nations in tonight's contest in Moscow and are perform their pop-rock Et Cetera.
Only 10 will be chosen from the line up this evening which includes Dutch entry Believe Again which has been co-written by Boyzone's Ronan Keating.
Dubliner Sinead (21) said that they are the only all-girl band in the competition and they are feeling confident about their performance.
"Our song is all about having fun and girl power," she said. "We're well rehearsed and we're excited about getting on the stage."
And friends and family have flown out to Moscow to cheer on the singers.
"I am looking forward to my mam and dad and my whole family arriving today," Sinead said. "They are so proud of me -- it will be great to have my family there for a bit of normality and to give me some advice.
"It's been a whirlwind -- we've been to so many events," she added. "It will be a brilliant moment being on stage in front of 20,000 in the audience."
The Aer Lingus air hostess has been trying out different costumes during the Eurovision rehearsal period and has chosen a black outfit and long hair extensions to give her a "rock chick" look.
"My outfit is a cross between Katy Perry and Avril Lavigne," the singer explained. "It will be completely different from anyone who has ever represented Ireland before."
Their song Et Cetera was written by Niall Mooney, Jonas Gladnikoff, Daniele Moretti and Christina Schilling and was released by Sony BMG on May 1.
Bookies are predicting that the song will make it into the final, but Paddy Power believes that Et Cetera will only secure 10th place.
However, it is a long shot to win this year's Eurovision with bookies giving the song odds of 125/1.
"Ireland are a massive price to win outright as the competition is fierce but you never know we could be in for a surprise on the night," said Nicola McGeady, from Boylesports.
Tonight's successful acts will join the 10 that passed through Tuesday night's semi-final and the five automatic qualifiers France, Germany, Spain, the UK and host country Russia in Saturday night's final.
