Answer by taking a quote from the following article:

Andrea Jane Corr MBE (born 17 May 1974) is an Irish musician, songwriter, and actress. Corr debuted in 1990 as the lead singer of the Celtic folk rock and pop rock group The Corrs along with her three elder siblings Caroline, Sharon, and Jim. Aside from singing lead vocals Corr plays the tin whistle, the ukulele, and the piano.

While her siblings were on hiatus to raise their families, Andrea launched a solo career. She released her first album, Ten Feet High, on 25 June 2007. It was produced by Nellee Hooper, who has worked with Gwen Stefani and Madonna; Bono was an executive producer. Her first single, "Shame on You" was an up-tempo pop song about men and women going to war and leaving behind partners they may never see again. It received positive reviews from music critics; IndieLondon described the song as a "slick package" that was "polished, well produced and with a message that's difficult to ignore". Losing Today's David Adair gave the song a strong review, writing that Corr's vocals were "crisp and uplifting". Liverpool's Daily Post gave the song a three-star rating, commenting that it was "deceptively upbeat", which masked its "heavier message about conscription and war".  On 10 April 2009 Andrea announced on Claudia Winkleman's BBC Radio 2 show that she would be releasing a second album of old songs and covers. She spoke of her disappointment and how 'gutted' she had been when her 2007 album Ten Feet High had failed to gain commercial success. She also spoke at length of her experiences while acting in the play Dancing at Lughnasa and how it has given her hope for upcoming projects, including a second solo album of 'old songs'.  In late January 2011, her new album was announced for "early summer", and a downloadable MP3 of her cover of John Lennon's Number 9 Dream was made available to subscribers. Lifelines was released on 30 May. In the summer of 2012, she re-recorded the track "Pale Blue Eyes" (which had first appeared on her album "Lifelines") with German electronic musician Christopher von Deylen, better known under his alias Schiller. It was released in Germany on 5 October on the Schiller album Sonne.
