Singer Alicia Keys has released a track titled "Zebras and airplanes" that she recorded five years ago.

The 33-year-old released the track on her website AKVault, which was launched late last year, reports aceshowbiz.com.

In the track, Keys talks about being free and able to go wherever she likes.

Keys said that "Zebras and airplanes" was inspired by a painting by Chloe Early.

"I had never been overcome to write a song after seeing a painting before, but this one sent me to another place," she explained on her website.

"I felt it! The power, the freedom, the strength to gallop and fly. And I knew right at that moment I would write a song called 'Zebras and airplanes' to describe that kind of love. The whole of you-body and soul-can gallop and fly," she added.
