E.SO is back with a new single named 'Black Ocean.' 

The song describes a love that is as beautiful as the ocean, but if you fall too deep in it, it turns into a black ocean. At first glance, the song seems dark and heavy, but adding a tropical genre with a cool sound suitable for the sea, it turned into a song that can be listened to without pressure. The singer also participated in writing to enhance the authenticity of the song.

E.SO (이소) is a soloist under A.I.M by Enterarts. She is a former member of the girl group Berry Good under the name Seoyul (서율). She made her solo debut on July 16, 2021, with the digital single 'Orgel.'
