Singers IU and Ulala Session revealed their collaboration teaser of song "Anxious Mind."

On June 27, N.A.P Entertainment revealed the "Ice Cream Audio Player" of IU and Ulala Session's "Anxious Mind" through their official Youtube channel.

"Anxious Mind" is the fifth song in Producer Choi Gap Won's project "The Lyrics." Although recorded in 2012, the song has delayed its release due to the death of Lim Yoon Taek.

The song "Anxious Mind" is reminiscent of the 80s sound, with synth sounds and refreshing images as its motif.

The song is composed by Kim Do Hoon, producer of Soyou and Junggigo's "Some," and PJ, who has made the first Japan Oricon #1 song as a Korean composer. The lyrics were written by Choi Gap Won.

Meanwhile, the project has incorporated skilled musicians like Wheesung, Soul Star, Youngji, Big Mama's Lee Ji Young, and Gummy since 2012.
