THEY are already an international sensation - thanks to You Tube - and now the Mona Lisa Twins are among the line-up for Wirral's fourth Festival of Firsts.
The Austrian duo will perform at the Concourse in West Kirby on the festival's opening day, Saturday July 5, and outside Chantilly’s in Hoylake on July 12.
The 19-year-olds gave a taste of what Wirral audiences can expect during a launch for the festival at the Holiday Inn, Hoylake on Thursday.
Lisa told the Globe: "We haven't played the festival before, so we're looking forward to taking part next month.”
Their repertoire features original material, as well as work by The Beatles.
Mona said: "We grew up working on music in the studio, and were influenced by many groups, including The Beatles and Simon & Garfunkel. We are always writing new music."
Thanks to You-Tube, their music has reached a worldwide audience, as Lisa explained: "We have just reached three million viewers, which is fantastic."
The girls moved to Southport two months ago and say they have never been busier. They are booked for a number of festival dates over the summer.
They also appear on Billy Butler’s Radio Merseyside show every weekend.
The girls are managed by Southport-based writer and illustrator Tim Quinn - who worked for Marvel Comics founder Stan Lee, working on his Incredible Hulk and Avengers comic books series.
He discovered Mona Lisa Twins by chance when looking for a present for his wife’s 64th birthday.
Tim told the Globe: "I found a version of The Beatles When I’m 64 on You-tube by the girls. What they did with Paul McCartney's song was remarkable.
"They have a real feel for 60s music; that’s because at the age of 13 they discovered The Beatles.
"They dismantled the Fab Four's songs, to see how Lennon, McCartney, Harrison and Starkey did it and they found the answer.
"After watching their stuff on You-Tube, I emailed them to ask if they had representation in the UK. Much to my delight they didn't.
"When people come to see them, they are completely blown away."
