Trot singer Hong Isak continues his musical journey with the release of his sixth mini-album, "Castle In The Air."

The EP, released at 6 p.m. on the 23rd, contains a total of five tracks, including the title song "Doesn't Matter." This album tells the story of modern people wandering between ideals and reality, expressing through music the journey of accepting one's imperfect self in a vast world and finding the freedom to live for today.

Last month, Hong Isak performed a passionate live show on a festival stage, wearing a black short-sleeve T-shirt and jeans, holding a microphone with a bright smile. The stage combined natural scenery and structural elements, creating a warm atmosphere, and his friendly interaction with the audience stood out.

As a singer and singer-songwriter who has been steadily loved, Hong Isak recently showed his affection for the local community by donating hometown love funds for Jeju together with star singers from the TOP10 of "Sing Again 3."

Meanwhile, it is known that Hong Isak is currently preparing for a nationwide tour concert to coincide with the release of this album. Expectations are rising for his future activities as he continues to meet the public with diverse musical colors and sincere lyrics.
