Art draws the Singer's attention

She also wrote lyrics for the last song in the album, titled Immense Beauty, in which she sings "finally we get together in the wheat field, immense beauty and celebration".

"I dedicate this song to Van Gogh's Wheat Field series. I felt like it's beautiful to sing these lyrics, which are not only about darkness but also hope. It's a sense of closure for the album," says Sun.

The singer, who was born in Singapore and started learning piano at 5, wrote her first song, Someone, while studying at Nanyang Technological University.

She then joined a music school founded by brothers Paul and Peter Lee, both Taiwan-based songwriters and producers. In 2000, she released her self-titled album, which was an instant success.

At a recent news conference in Beijing, Paul and Peter Lee showed up, which made Sun cry.

"I remember that first time we met in the school and she was just a young girl. Now, she is all grown up and clearly knows what she wants," says Paul Lee.

Sun says: "They have been my mentors for about 20 years and it's really touching to have them with me for so many years." The brothers are the producers of Sun's new album.

"Looking back, it's quite like a dream. I am a little bit overwhelmed. Music has always been a big part of my life. I have been doing concerts in my bathroom since I was young, envisioning everything I have now," says Sun. "And as long as I enjoy the process, I will go for it. Music is food for soul."

In 2011, Sun married her Dutch-Indonesian boyfriend, Nadim van der Ros, and one year later, she gave birth to a son.

She then kept a low profile until returning to the limelight with her album, Kepler, in 2014, which was followed by an 18-month-long tour.

"Motherhood changed me. When you are single, you have all the time in the world but now you have to take care of him," says Sun. "I do sing for him before bedtime and sneak out after he falls asleep."

The song, Rainbow Bot, which released in 2016, was dedicated to her son.
