ASTRO, release title song 'Knock'!

ASTRO's new album is being unveiled little by little.

ASTRO (MJ, Jinjin, Cha Eun-woo, Moon Bin, Rocky and Yoon San-ha) drew attention by releasing the title track "Knock" of its seventh mini album "GATEWAY" on April 21 through its official SNS channel.

Arriving past the previously unveiled bridge over the blue sea means a door to a new world.  Bright and dreamy light flows through the cracks in the open door of the title poster, drawing attention.

Among them, GATEWAY and Knock to open the door are connected to each other, completing the title track "Knock," further stimulating questions about the story to be released from the new song.

In addition, renowned lyricist and composer Jin will participate in the title track "Knock," raising expectations.  In particular, Isran, who showed emotional lyrics while working with BTS, SHINee, Red Velvet and GOT7, wrote the lyrics, adding to the level of perfection. Also, ASTRO's Jinjin and Rocky always participate in the rap making of the title track of this album, drawing attention.

Meanwhile, Astro's seventh mini album 'GATEWAY' will be released on May 4.
