Acoustic pop singer Dido shot to fame a decade ago as the soft crooner on US rapper Eminem's hit song, "Stan." After what she calls "disappearing" for a while, she is back this week with her first album in five years, now with a more electronic sound.

The London-based singer, 41, has sold more than 29 million albums since her debut album No Angel in 1999.

Girl Who Got Away was released in the US on Tuesday.

"It's a little comment on the fact that I disappeared a bit. That's what everyone else was pointing out to me that 'it's a perfect title for you'," Dido told Reuters.

"The song is about so many things for me. It's about that restlessness and having a dream of another life that you can't quite get to," she added.

Girl Who Got Away features an updated sound from the singer with heavier bassline beats, folk and electronic influences, which Dido attributed to her brother and producer, Rollo Armstrong.

Dido found mainstream success in 2000 after rapper Eminem featured a sample of her track "Thank You" on his hit song "Stan."

The exposure helped the singer's 2003 Life For Rent album to land at No.4 on the Billboard 200 album chart that year.

Her 2008 album Safe Trip Home was less successful albeit critically acclaimed.

In 2011, the singer become a mother for the first time with husband Rohan Gavin to son Stanley - not named after the Eminem song, Dido was quick to clarify.
