Zhang, who rose to fame after winning the 2005 Supergirl singing competition, is known for singing in various languages, such as English, French and Spanish, in addition to Mandarin.

She is also known for hitting the high notes, which is why she is known as "Dolphin Voice". Zhang has been compared to Mariah Carey, whom she has admired since she was a teenager.

Her five studio albums and two EPs released since 2006 have all topped the Chinese music charts. She has also won best female singer awards over the past three years.

"I have been trying to sing in different styles because I want to find a style that belongs to (me)," she says. "I love music, but during the past seven years, I just wasn't enjoying myself singing."

She claims she couldn't even look at herself in the mirror - when practicing - and felt awkward when dancing on stage.

Zhang, from Chengdu, capital of Sichuan province, says she had been planning the live album for some time.

Through it she rediscovered her joy of singing and the pleasure of expressing her own ideas.
