Amber Liu from f(x) talks to Billboard about new album

“White Noise” and “Lost at Sea” have two different ideas behind them. Why did you decide to release them as a paired set?

The producers on the tracks, Darren [Smith] and Sean [Alexander], I’ve been working with them for many years now and I think this was around that era of me trying to just try new things. And they were very, very supportive of doing that. I just thought that the EDM-inspired elements definitely sound-wise paired really well. But also it’s the progression of my story, I guess. I wrote both songs at similar times, so I thought this is the next step of the story that I want to show to people.
