Just because the year is winding down doesn't mean we're done with Pharrell-related work. His latest feature delves more into the art world rather than music, however.

Pharrell hosts a YouTube series called 'ARTST TLK,' where he sits down with various artists to interview them about a variety of topics. His latest guest is Jeff Koons. The 58-year-old artist is known for producing artwork out of average objects, like remaking balloon animals with stainless steel.

In a sneak peek of their sit-down, the two talk about Koons' approach to art and the idea of experimental art. Koons states his use of reflective surfaces makes his art more about the people reflected on the surface, which he feels accomplishes what avant garde should focus on.

"That's what I love about the avant garde -- it's about people interacting with each other," Koons says. "You can change your life. You can change the life of others.

Previous 'ARTST TLK' guests include Spike Lee, KAWS and Tony Hawk.
