Singer and actor Do Kyung-soo (D.O.) has released a portion of the music video for "Guitarist," the title track of his fourth mini-album.

The new album, "DOPAMINE," explores the excitement of everyday life and the pleasure of love through a variety of genres. The title track, "Guitarist," is a song that combines sensual guitar sounds with D.O.’s signature, unrivaled vocals over a restrained rhythm based on R&B and soul. Notably, Penomeco, who previously collaborated with D.O. on "Fit" and "DUMB," participated in writing the lyrics, delicately expressing the heart-fluttering emotions between the two.

Meanwhile, D.O.’s fourth mini-album, "DOPAMINE," will be officially released on various online music sites at 6 p.m. on the 8th.
