ZICO, set to make a comeback on Sept. 30, unveiled a tracklist for its first full-length album in a surprise move.

Zico posted an image of his first full-length album "THINKING" Part.1 tracklist in eight years on its official SNS, heightening the comeback fever.

According to the released tracklist, the album included a total of five tracks, including the double title track "Daredevil" and "Human," as well as "Not Him," "Polar" and "One-man Show."

The title track "Daredevil" featured Jvcki Wai, who has been noted for his individual style and musicality, and Yeom Ta-ra, who recently emerged as a hot rapper in a hip-hop scene, while the  song "One-man Show" featured a trend rapper Sik-K, signaling a perfect musical synergy.

The song "One-Man Show" was first released at a "Fanxy Child" cruise concert in August, which garnered an enthusiastic response.

In particular, ZICO released another title song "Human" on various stages, including the Joy Olpark Festival and the University Festival, and is already showing signs of a big hit.

ZICO's first full-length album "THINKING" Part.1 captures the self-portrait of a young man from his own mind.

It's a book-like album that combines what you've felt, experienced, and honest stories about yourself.

Since ZICO is the first full-length album, he has participated in writing and composing songs as well as actively participating in music videos and also has performed brilliantly as a storyteller.

Meanwhile, the company will release its first full-length album "THINKING" Part.1 at 6 p.m. on Sept. 30 and begin full-fledged comeback activities.
